Description

Technical Field

[0001] The utility model relates to the technical field of fuse production equipment, in particular to a fuse two-end outer cap assembly machine. Background Art

[0002] The porcelain tube and outer cap of the existing fuse are usually assembled in a semi-automatic manner, and usually have a pressing mechanism. The pressing mechanism usually has a turntable that clamps the porcelain tube. Through the pre-process, the porcelain tube of the fuse is clamped on the clamp around the turntable to complete the assembly of the outer cap at one end of the porcelain tube. The porcelain tubes that need to be pressed with the outer cap are sent to the pressing station in sequence through the turntable. The workers manually place the outer caps on the two ends of the porcelain tube of the pressing mechanism. Then the workers operate the pressing mechanism to press the outer cap on the second end of the product, and then remove the porcelain tube for the next pressing of the outer caps at the two ends. This method is not efficient enough, and the workers have a high workload. There are usually non-circular structures such as touch knives on the outer caps at the first and second ends of the porcelain tube. According to the process requirements, the touch knives on the outer caps at the first and second ends of the porcelain tube need to be aligned. Therefore, the angle of the outer cap needs to be manually adjusted during pressing, which reduces the assembly efficiency, and manual visual alignment is prone to deviations and the accuracy is not high enough.

The beneficial effects of the utility model are as follows: the utility model provides a fuse two-end outer cap assembly machine. Compared with the prior art, the utility model has at least the following technical effects: 1. The outer caps are loaded one by one onto the outer cap positioning and feeding track by a vibrating outer cap loading tray, and the outer cap moving fork mechanism pushes the outer caps forward one by one at equal intervals to the picking position of the outer cap picking device, and the positioning and loading of the outer caps is realized by the setting of the outer cap positioning and feeding track, which is convenient for the outer cap picking device to accurately clamp the positioned outer caps from the outer cap positioning and feeding track and place them on the outer cap assembly push rod, and the outer cap push rod flipping assembly and the outer cap pressing drive cooperate to complete the outer cap flipping and press-fitting with the two ends of the product, so as to replace manual loading and reduce manual intervention; the outer cap positioning and feeding track and the outer cap moving fork mechanism cooperate to complete the positioning of the outer cap in the early stage, and there is no need to adjust the angle of the outer cap again during the pressing process, which helps to improve the pressing efficiency of the outer cap and the product (i.e., the porcelain tube of the fuse). 2. Since the outer cap can only be loaded with the port facing upwards when the outer cap vibrating loading tray is loaded, but the two ends of the product are usually facing upwards, it is necessary to use the outer cap push rod flipping assembly to drive the outer cap to flip so that its port faces downwards during the press-fitting process to ensure that the outer cap can be accurately pressed to the two ends of the product. 3. The outer cap push rod flipping assembly for installing the outer cap assembly push rod is installed on the outer cap slide. The displacement of the outer cap slide facilitates the outer cap assembly push rod to move to the material receiving station to receive the outer cap sent by the outer cap picking device. After that, the outer cap is flipped by the outer cap push rod flipping assembly, and the outer cap slide moves to the pressing station to move the outer cap on it to the two ends (upper ends) of the product, which can effectively avoid the possible mutual interference between the picking device and the outer cap pressing and pressing device. 4.

A positioning clamp is provided on the side of the loading hole of the outer cap assembly push rod, and the clamping force is provided by the connecting spring, so that when the outer cap is pressed into the loading hole, the positioning clamp can buckle the end face of the outer cap to prevent it from falling out of the loading hole during the flipping process; after being pressed onto the two ends of the product, due to the small clamping force of the connecting spring, a force is generated to pull the outer cap downward during the upward movement of the outer cap assembly push rod. During this process, the positioning clamp is pushed away by the outer cap, and the outer cap can fall out of the loading hole. 6. An outer cap material shifting mechanism and a material discharge block are provided to facilitate the cooperation with the outer cap moving fork mechanism to realize the equidistant pushing of the outer cap. The material discharge block blocks the outer cap from the outer cap feeding vibration plate. After the outer cap moving fork mechanism is pushed forward a specified distance and reset, an outer cap is shifted through the material discharge block by the outer cap material shifting mechanism, and the equidistantly arranged receiving grooves of the fork plate are cooperated so that the outer cap can always keep moving forward at an equal distance, which is convenient for subsequent material removal.7. By setting a defective outer cap unloading device on the outer cap positioning and feeding track, the defective products can be detected in time by the first optical fiber sensor therein, and the defective product driving assembly and defective product unloading parts set at the unloading notch of the outer cap positioning and feeding track can be used to remove the defective products from the outer cap positioning and feeding track, so as to avoid the assembly of defective outer caps on the products, which is helpful to improve the yield of subsequent finished products and improve the overall production efficiency. 8. The outer cap picking device can penetrate the outer cap and take out the outer cap through the expansion or contraction of the expansion shaft, so as to avoid the problem that the traditional clamping method may cause the outer cap to be deformed and unable to be assembled, and because the expansion shaft contacts the entire inner circumference of the outer cap when taking the outer cap, the increase in the contact surface and the dispersion of the force can avoid deformation on the one hand, and on the other hand, it can avoid the outer cap from falling off during the movement as much as possible, and the expansion shaft does not rotate, so the angle of the outer cap will not change during the clamping movement.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] See also Figures 1 to 11A fuse two-end outer cap assembly machine comprises an outer cap vibrating loading tray 1, and also comprises a track feeding device 2, the track feeding device 2 comprises an outer cap moving fork mechanism 23 and a detachable outer cap positioning feeding track 21, the outer cap moving fork mechanism 23 is arranged beside the outer cap positioning feeding track 21; one end of the outer cap positioning feeding track 21 is docked with the outlet of the outer cap vibrating loading tray 1, the other end of the outer cap positioning feeding track 21 is docked with an outer cap picking device 3, the outer cap picking device 3 is also docked with an outer cap flipping and pressing device 4, the outer cap moving fork mechanism 23 is used to move the outer cap on the outer cap positioning feeding track 21 from one end Push to the other end; the outer cap flipping and pressing device 4 includes an outer cap assembly push rod 41, an outer cap push rod flipping component 42, and an outer cap pressing driving component 43. The outer cap assembly push rod 41 is arranged on the outer cap push rod flipping component 42, and the outer cap push rod flipping component 42 is opposite to the outer cap pressing driving component 43. The outer cap picking device 3 is used to transfer the outer cap at the other end of the outer cap positioning feeding track 21 to the outer cap assembly push rod 41, the outer cap push rod flipping component 42 is used to flip the outer cap assembly push rod 41 thereon, and the outer cap pressing driving component 43 is used to push the outer cap assembly push rod 41 to move the outer cap thereon to be pressed onto the two ends of the product. The outer cap vibrating loading tray 1 is used to load the outer caps one by one to the outer cap positioning and feeding track 21, and the outer cap moving fork mechanism 23 pushes the outer caps forward one by one at equal intervals to the picking position of the outer cap picking device 3. The positioning and feeding of the outer cap is realized by setting the outer cap positioning and feeding track 21, so that the outer cap picking device 3 can accurately clamp the positioned outer caps from the outer cap positioning and feeding track 21 and place them on the outer cap assembly top rod 41. The outer cap top rod flipping assembly 42 and the outer cap pressing drive 43 cooperate to complete the outer cap flipping and press-fitting with the two ends of the product, so as to replace manual loading and reduce manual intervention; the outer cap positioning and feeding track 21 and the outer cap moving fork mechanism 23 can cooperate to complete the positioning of the outer cap in the early stage, without adjusting the angle of the outer cap again during the pressing process, which helps to improve the pressing efficiency of the outer cap and the product (i.e., the porcelain tube of the fuse). The preferred outer cap pressing drive 43 is a telescopic cylinder, or it can be other driving mechanisms that can achieve linear displacement, but it is not limited to this. The outer cap positioning and feeding track is designed to be detachable, so that the outer cap structure that can be pressed in as needed can be replaced with the corresponding outer cap positioning and feeding track.

The outer cap pressing drive member 43 is used to press down and drive the outer cap assembly top rod 41 after flipping downward to press the outer cap at the lower end onto the two ends of the product. Since the outer cap vibration loading tray 1 can only load the outer cap with the port facing upward, but the two ends of the product are usually the ends facing upward, it is necessary to use the outer cap top rod flipping assembly 42 to drive the outer cap to flip so that its port faces downward during the pressing process to ensure that the outer cap can be accurately pressed to the two ends of the product. The preferred flip driving member 422 is a rotary cylinder, but may also be a motor, but is not limited thereto.

The displacement of the outer cap slide 423 facilitates the outer cap assembly push rod 41 to move to the material receiving station to receive the outer cap sent by the outer cap picking device 3, and then the outer cap is flipped by the outer cap push rod flip assembly 42. The outer cap slide 423 is driven by the sliding drive 424 to move to the pressing station to move the outer cap thereon to the two ends (i.e., the upper end) of the product, which can effectively avoid the mutual interference that may occur between the picking device and the outer cap pressing and pressing device.

[0047] The utility model has the following working principle:

[0048] The outer cap is fed from the outer cap vibrating loading tray 1 by spiral vibration to one end of the outer cap positioning feeding track 21, and the outer cap will be blocked by the discharge block 24 on the left and right of the outer cap positioning feeding track 21 under the action of the spring force of the discharge spring 25, and the first optical fiber sensor detects whether it is in place, and then the material discharging rod 222 of the material discharging multi-axis moving assembly 221 installed in the outer cap material discharging mechanism 22 moves downward, so that the lower end of the material discharging rod 222 is inserted into the inner wall of the outer cap, and then the material discharging multi-axis moving assembly 221 drives the material discharging rod 222 to move from one end of the outer cap positioning feeding track 21 to the other end, so that the material discharging rod 222 drives the outer cap to pass through the discharge block 24 and then moves to an equidistant position and then stops. Then the material discharging multi-axis moving assembly 221 is reset, so that the material discharging rod 222 is reset to the initial position.

[0049] After the outer caps are placed at equal intervals on the outer cap positioning and feeding track 21, the fork moving assembly 231 drives the fork plate 232 to approach the outer cap on the outer cap positioning and feeding track 21 so that the accommodating groove 233 on the fork plate 232 is inserted into the outer shape of the upper end of the outer cap, and then the fork moving assembly 231 drives the fork plate 232 to move toward the other end of the outer cap positioning and feeding track 21, so that the outer cap on the outer cap positioning and feeding track 21 reaches the detection point of the first optical fiber sensor 53, and the first optical fiber sensor 53 detects whether there is a paper pad at the bottom of the inner wall of the outer cap. If no paper pad is detected, the outer cap is determined to be a defective product, and the defective outer cap unloading device 5 designed at the middle and rear end position of the outer cap positioning and feeding track 21 is used to unload the outer cap. Then the fork moving assembly 231 resets the fork plate 232 to its initial position, and repeats this action so that the outer caps sequentially shift the materials until the outer cap positioning and feeding track 21 is full, and an outer cap baffle 26 is installed at the other end of the outer cap positioning and feeding track 21 for limiting, and the second optical fiber sensor detects whether there is a lack of material. If material is detected, all the actions of the front end will be paused (i.e., stop moving the outer cap on the outer cap positioning and feeding track 21). If the lack of material is caused by the unloading of defective outer caps, the operation will continue until the second optical fiber sensor detects the presence of material.

[0050] After the outer cap reaches the other end position of the outer cap positioning feeding track 21, the multi-axis moving assembly 31 on the outer cap picking device 3 drives the expansion shaft 32 to insert the lower end position of the expansion shaft 32 into the inner wall of the outer cap, and then the expansion shaft driving component 33 drives the inner core expansion rod to move upward, so that the outer tube expands and tightens the inner wall of the outer cap at the same time, and then the multi-axis moving assembly 31 drives the expansion shaft 32 to clamp the outer cap and move upward, and move to the outer cap flipping and pressing device 4 Just above the outer cap assembly push rod 41, and then the multi-axis moving assembly 31 drives the expansion shaft 32 to move downward, so that the outer cap is directly inserted into the loading hole 411 on the outer cap assembly push rod 41 and pushes open the positioning frame, so that the outer cap is loaded into the loading hole 411, the expansion shaft driving component 33 causes the inner core expansion rod to move downward, so that the outer tube resets and shrinks and separates from the outer cap, and then the multi-axis moving assembly 31 causes the expansion shaft 32 to return to its original position.

[0051] When the clamp of the turntable clamps the porcelain tube of the fuse and enters the outer cap flipping and pressing device 4 (the structure of the turntable can be found in the patent content with announcement number CN210837615U, which is not explained in detail), the outer cap is placed in the loading hole 411 of the outer cap assembly push rod 41 of the outer cap flipping and pressing device 4, and the flipping driving member 422 of the outer cap push rod flipping assembly 42 drives the flipping guide seat 421 to flip 180° so that the outer cap faces downward (in this process, the contact thereon will hit the upper rotation limit block 425 to position the flipping guide seat 421), and the sliding driving member 424 on the outer cap flipping and pressing device 4 drives the outer cap slide plate 423 to move toward the porcelain tube, so that the outer cap assembly push rod 41 reaches the position directly above the porcelain tube of the fuse on the clamp of the turntable. Then the outer cap pressing driving member 43 moves downward to push the outer cap assembling push rod 41, so that the outer cap assembling push rod 41 moves downward, and the outer cap pressing driving member 43 is checked by the close opening clamp to see whether it is in place. Then the outer cap in the filling hole 411 of the outer cap assembling push rod 41 is pushed into the upper end (i.e., the two ends) of the porcelain tube, and the lower end surface of the porcelain tube is pressed against the working surface of the outer cap lower pad 46. The pressure sensor 47 installed under the outer cap lower pad is used to monitor the pressure value when pressing the cap, and the displacement sensor 48 and the outer cap assembly are used to monitor the pressure value when pressing the cap. After the sensor sheet on the installation push rod 41 detects that the displacement of the outer cap press-fitting meets the data range of the technical requirements, the outer cap pressing driving member 43 is reset, so that the outer cap assembly push rod 41 receives the action of the reset spring 45 and moves upward away from the upper end of the porcelain tube to reset the outer cap, and then the sliding driving member 424 drives the outer cap slide plate 423 away from the porcelain tube to reset, and then the flip driving member 422 drives the flip guide seat 421 to reset, so that the outer cap assembly push rod 41 rotates 180° back to the initial position, completing the outer cap pressing assembly work at one end. This cycle is repeated.
