Description

Technical Field

[0001] The present invention relates to a test labeling device, and more particularly to a test labeling device for fuses. Background Art

[0002] In recent years, with the continuous deterioration of the global environment, the protection of the ecological environment has received more and more extensive attention from all sectors of society. As the main culprit of greenhouse gas emissions, the exhaust emissions of fuel vehicles are increasingly polluting the environment. To reduce this harm, electric vehicles have emerged. Electric vehicles use electric energy as the driving energy and have the advantages of high efficiency and zero emissions, so their production volume increases year by year.

[0003] At present, electric vehicle protection requires the use of fuses to protect the whole vehicle against short circuits or overloads. Therefore, fuses are one of the most important electrical components in electric vehicles. However, at present, the resistance measurement and labeling processes of fuses mainly adopt the manual assembly line operation method, which is prone to errors such as missing the placement of unqualified products, inaccurate products and labeling, and cannot guarantee production consistency and low efficiency. Summary of the Invention

[0004] To solve the above problems, the present invention provides a test labeling device for fuses, which realizes the automatic measurement and labeling of fuses by providing a resistance detection station, a rotating station and a label taking and labeling device.

[0027] Now referring to the accompanying drawings, a schematic solution of the device disclosed by the present invention will be described in detail. Although the accompanying drawings are provided to present some embodiments of the present invention, the drawings do not have to be drawn according to the dimensions of specific implementation schemes, and certain features may be enlarged, removed or sectioned locally to better show and explain the disclosure of the present invention. Some components in the drawings can be adjusted in position according to actual needs without affecting the technical effects.

[0028] Some directional terms used hereinafter to describe the drawings will be understood to have their normal meanings and refer to those directions involved when normally viewing the drawings. Unless otherwise specified, the directional terms described in this specification are basically in the conventional directions understood by those skilled in the art. Among them, "longitudinal" means Figure 1 the length direction of the conveying device represented by "X" in Figure 1 the width direction of the conveying device represented by "Y" in Figure 1 the height direction of the entire test labeling device represented by "Z" in

[0029] Figure 1 and Figure 2A three-dimensional schematic diagram of a test labeling device according to the present invention is shown from different perspectives. The test labeling device is mainly designed for fuses, aiming to first measure the resistance of the fuses, and then decide whether to label the fuses according to the measurement results and perform the subsequent labeling process accordingly. The fuse mainly includes a fuse tube and two outer caps arranged at both ends of the fuse tube. In addition, a contact blade is connected to each outer cap. Labeling the fuse mainly means attaching a label to the entire or partial outer peripheral wall of the fuse tube according to the size of the label. Of course, the test labeling device according to the present invention is not limited to being applied to fuses, and other components with similar working principles and shapes to fuses can also be tested and labeled using the test labeling device according to the present invention.

[0030] The test labeling device of the present invention mainly consists of a resistance detection station 1, a rotation station 2, a conveying device 6, a label feeding device 3, a label picking and labeling device 4, a sorting station 7, etc. First, the resistance of the fuse is measured at the resistance detection station 1, and the resistance detection station 1 sends the measurement result to a controller (not shown). Next, the conveying device 6 conveys the fuse to the rotation station 2, and the rotation station 2 will clamp at least one end of the fuse, for example, it can clamp one or two outer caps, and of course, it can clamp one or two contact blades. If the measured resistance value meets the standard, then under the control of the controller, the label feeding device 3 will provide a label that has been peeled off from its backing paper, and the label picking and labeling device 4 will pick up the label from the label feeding device 3 and make the label at least partially adhere to the outer peripheral surface of the fuse tube located at the rotation station 2. Next, the rotation station 2 drives the fuse to rotate, and the label picking and labeling device 4 abuts against the label adhered to the fuse tube to press the entire label against the outer peripheral surface of the fuse tube as the fuse rotates. The sorting station 7 is arranged downstream of the rotation station 2 and includes at least two sorting channels 71 for qualified products and unqualified products to pass through respectively. If the resistance detection value does not meet the standard, then the subsequent labeling steps will not be executed, and the controller will control the sorting station 7 to move horizontally so that the unqualified fuses enter the corresponding sorting channels 71.

[0031] Specifically, as Figure 3As shown, the resistance detection station 1 is constructed to include a resistor (not shown), two groups of detection chucks 11 arranged opposite to each other in the transverse direction, and a second vertical displacement mechanism 12 for driving the detection chucks 11 to move vertically up and down, wherein each group of detection chucks 11 can serve as two measuring ends of the resistor. When resistance detection is not performed, the detection chucks 11 are in an elevated position. When the fuse is transferred to or directly placed vertically below the detection chucks 11, the second vertical displacement mechanism 12 drives the detection chucks 11 to descend, and each group of detection chucks 11 respectively clamps the outer peripheral wall of an outer cap to position the fuse and electrically connect it to the outer cap, thereby forming a closed loop between the fuse and the resistor to achieve resistance measurement of the fuse. When the measurement is completed, the detection chuck 11 is raised again under the drive of the second vertical displacement mechanism 12 to release the fuse, allowing it to be taken out or transferred to the next station. Of course, it should be understood by those skilled in the art that the detection chuck 11 is not limited to Figure 3 The form of being clamped on the outer peripheral wall of the outer cap is shown in the figure. For example, the detection clamp 11 can be designed to be pressed against the end faces of the two end caps facing away from each other in the lateral direction, which can also achieve electrical connection with the two end caps.

[0032] Figure 4 The preferred structural schematic diagram of the rotating station 2 is shown. The rotating station 2 is mainly used in conjunction with the labeling device 4 described in detail below to position, clamp and rotate the fuse. Specifically, the rotating station 2 is constructed to include two rotation limit seats 22 arranged opposite to each other in the transverse direction and a rotation limit member 21 arranged vertically above each rotation limit seat 22. An arc-shaped recess conforming to the outer peripheral wall of the outer cap is provided on the end face of the rotation limit member 21 facing the rotation limit seat 22. The rotation limit member 21 presses the outer peripheral walls of the two outer caps against the rotation limit seat 22 by means of the arc-shaped recess. The rotating station 2 also includes a first telescopic mechanism 24 and a rotation driving mechanism 23. The first telescopic mechanism 24 is designed to drive the rotation limit member 21 to rotate by means of a driving connecting rod so as to be lifted and lowered relative to the rotation limit seat 22. When the rotation limit member 21 is lifted relative to the rotation limit seat 22, the fuse can be inserted or removed. When the rotation limiter 21 falls about the rotation limiter seat 22, the fuse is fixed in place relative to the entire rotation station 2. The rotation drive mechanism 23 is designed to drive the rotation limiter seat 22 and the rotation limiter 21 to rotate synchronously, thereby driving the fuse clamped therebetween to rotate, and the specific rotation direction can be set as needed.

[0033] Of course, those skilled in the art will appreciate that the rotating station may also adopt other types of arrangements to achieve the functions of clamping and rotating the fuse. For example, the rotating station may adopt two claws that can be opened and closed to clamp and release, for example, the contact blade of the fuse and thereby drive the entire fuse to rotate. The rotating station may also adopt the form of two components extending from both ends of the lateral direction and pressing lower than the two ends of the end cap.

[0034] Figure 5 A perspective schematic view showing the label feeding device 3, wherein the label feeding device 3 is preferably arranged on the lateral side of the conveying device 6 described in detail below. The label feeding device 3 mainly includes a mounting plate 35 generally extending vertically and a label tape unwinding mechanism 32, a tensioning and guiding mechanism 33, a peeling mechanism 31, and a label tape winding mechanism 34 provided on the mounting plate 35. The label tape unwinding mechanism 32 includes an unwinding motor and an unwinding shaft. The unused label tape will be sleeved on the unwinding shaft in a roll shape and rotate with the unwinding shaft to provide a continuous label tape. The tensioning and guiding mechanism 33 mainly includes a tensioning rod 331 connected to a tensioning shaft (not shown), an upper limit sensor (not shown), a lower limit sensor (not shown), and a plurality of guiding shafts 332. The label tape will pass around each component of the above-mentioned tensioning and guiding mechanism 33 as required. The upper limit sensor and the lower limit sensor are respectively used to sense the highest position and the lowest position of the tensioning rod 331. When the movement of the tensioning rod 331, for example, rotates counterclockwise and falls within the sensing range of the upper limit sensor, the unwinding motor stops rotating; when the tensioning rod 331, for example, moves clockwise and falls within the sensing range of the lower limit sensor, the unwinding motor starts rotating, and so on in a cycle. Thus, it is ensured that the label tape is always in a tensioned state and is coordinated with the rhythmical operation of the peeling mechanism 31 described below.

[0035] The peeling mechanism 31 has a peeling plate 311, and the peeling plate 311 is provided with a peeling end 312 for separating the label from the backing paper, which is shown in more detail in Figure 6 The label tape will first travel along the upper end surface of the peeling plate 311 under the action of the above-mentioned tensioning and guiding mechanism 33. After passing around the peeling end 312, the label is separated from the backing paper. The backing paper will wind around the lower end surface of the peeling plate 311 and is taken back under the action of the label tape winding mechanism 34. The peeling end 312 can be designed to be, for example, a sharp blade shape. When the label tape passes through the peeling end 312, one end of the label will first break away from the backing paper, and the backing paper continues to travel under the action of the label tape winding mechanism 34, and the label and the backing paper are gradually separated. The peeling mechanism 31 with the above structure is particularly suitable for hard labels, but for soft labels or labels with a relatively high bonding strength with the backing paper, there may be a risk that the label and the backing paper cannot be smoothly separated, that is, the label will continue to travel with the backing paper and will eventually be taken into the winding mechanism. In addition, the peeling end may not be designed to be a sharp blade shape. For example, a peeling shovel can be provided in front of the peeling plate, but the peeling shovel must smoothly enter between the label and the backing paper to be effective.

[0036] Accordingly, the present invention further provides a peeling lever 313 vertically below the peeling plate 311. The backing paper separated from the label will wind around the peeling lever 313 and move under the drive of the peeling lever 313. At the same time, the peeling plate 311 and the peeling lever 313 are designed to perform a synchronous reciprocating beat motion along the first direction and the second direction opposite to each other. The first direction is selected to be parallel to the traveling direction of the label on the upper surface of the peeling plate 311, and the second direction is the direction opposite to the traveling direction of the label on the upper surface of the peeling plate 311. During label peeling, when the label to be peeled reaches the peeling end 312, the upper surface of the label can be sucked by the suction head 41 described in detail below. This step can be understood as keeping the label to be peeled stationary. At the same time, the peeling plate 311 and the peeling lever 313 are moved synchronously in the second direction. This step can be understood as the peeling plate 311 withdrawing from below the label to be peeled to create a peeling space. At the same time, the peeling lever 313 drives the backing paper at the space vacated by the peeling plate 311 away from the lower surface of the label to be peeled that has been held. After the label is successfully peeled, the peeling plate 311 and the peeling lever 313 move back to their original positions in the first direction for the next label to continue traveling to the peeling position. The synchronous beat motion of the peeling plate 311 and the peeling lever 313 can provide an instantaneous force for pulling the backing paper away from the lower surface of the label, which is particularly effective for soft labels. The peeling end is laterally aligned with the label picking mechanism when the peeling plate travels to the maximum stroke in the first direction.

[0037] The label tape winding mechanism 34 is as Figure 5 shown and mainly includes an elastic pressing member 341 and a winding shaft 342. Additionally, it is preferably arranged that a guide shaft is further disposed below the peeling plate 311, and the backing paper winds around the guide shaft after winding around the peeling lever 313. The elastic pressing member 341 mainly includes a turning roller and an elastic pressing member, and the elastic pressing member presses the backing paper tightly against the surface of the turning roller.

[0038] Figure 7 The figure shows a schematic diagram of a preferred structure of the label picking and applying device 4, which mainly includes a label picking mechanism and a label applying mechanism. The label picking mechanism is designed to pick up a label from the label feeding device 3 and partially attach the label to the outer peripheral surface of the melting tube located at the rotating station 2. Specifically, the label picking mechanism is configured to include a suction head 41, a first vertical displacement mechanism 42, and a first horizontal displacement mechanism 43. The suction head 41 can move vertically and horizontally under the drive of the first vertical displacement mechanism 42 and the first horizontal displacement mechanism 43. As Figure 8As shown, the suction head 41 includes a label suction member 44, on the lower end surface of which there is provided at least one suction hole (not shown), and the suction hole is in fluid communication with a negative pressure device (not shown) so as to form a negative pressure in the suction hole to adsorb the label. The peeling end 312 is preferably laterally aligned with the suction head 41 when the peeling plate 311 travels to the maximum stroke in the first direction. Thus, the suction head 41 only needs to perform lateral and vertical movements to transport the label, and there is no need to additionally perform longitudinal movement. Of course, those skilled in the art should understand that if affected by factors such as installation space limitations, a longitudinal displacement mechanism can also be provided for the suction head 41 to make it more flexible in sucking the label.

[0039] As described above, at the start of label peeling, the suction head 41 moves to the vertical upper side of the label to be peeled and sucks the label. When the label has been peeled, the suction head 41 laterally displaces with the label to the vertical upper side of the melting tube at the rotation station 2 and places the label on the outer peripheral wall of the melting tube. However, at this time, the bonding between the label and the melting tube is poor and it is easy to separate from the melting tube. Thus, a feasible way is for the suction head 41 to further descend vertically until the label closely abuts against the outer peripheral wall of the melting tube. Preferably, as Figure 8 shown, a pair of claw members 45 can also be provided on both opposite sides of the label suction member 44 in the longitudinal direction, and the pair of claw members 45 can rotate towards the label suction member 44 to perform closing and opening actions. When the claw members 45 are closed above the melting tube, they can press the outer peripheral surface of the melting tube, thereby pre-pressing a part of the label to the outer peripheral surface of the melting tube, achieving a pre-positioning effect and preventing the label from falling off during the subsequent rotation movement.

[0040] The labeling mechanism includes a rolling member 46 and a second telescopic mechanism 47 for driving the rolling member 46 to move towards or away from the rotation station 2. When the rolling member 46 retracts, it does not interfere with the normal operation at the rotation station 2. When the rolling member 46 extends, it will abut against the outer peripheral surface of the melting tube located at the rotation station 2. Thus, as the melting tube rotates, the entire label is adhered to the outer peripheral wall of the melting tube.

[0041] It can be seen that the labeling action according to the present invention is completed through the cooperation of the label picking mechanism and the labeling mechanism. The alternating operation of the two components improves the operating efficiency of the entire device, enhances the consistency of the labeling quality, and prevents the label from undesirably detaching from the product.

[0042] The label picking and labeling structure can also alternatively be completed by only one mechanism. For example, there is only one rolling member, the above-mentioned peeling end is arranged at the vertical upper side of the melting tube located at the rotation station. After the peeling plate moves in the second direction, the rolling member vertically descends and directly presses the label on the melting tube and then performs a rotation movement. However, this method has low efficiency and it is difficult to ensure that the label has been joined to the outer peripheral wall of the melting tube before rolling.

[0043] As described above, the label stripping process of the label feeding device 3 adopts a rhythmic operation mode. In order to continuously perform resistance detection and labeling for multiple fuses, the entire device preferably also adopts a rhythmic operation mode. However, since the time for resistance detection is significantly shorter than the operation time of the label picking and labeling device 4, in order to improve the operation efficiency, a buffer station 5 is preferably further provided between the resistance detection station 1 and the rotation station 2.

[0044] This buffer station 5 is configured as shown in Figure 9 to include a positioning press head 51 and a third vertical displacement mechanism 52 for driving the vertical displacement of the positioning press head 51. The positioning press head 51 may also include an arc-shaped recess. When the fuse is conveyed to this buffer station 5, the positioning press head 51 descends to accommodate the fuse in the arc-shaped recess to hold the fuse in place.

[0045] Figures 10 - 12 The schematic diagram of the conveying device 6 is shown. The conveying device 6 is configured to include a feeding mechanism 61 and a material conveying mechanism 63. The feeding mechanism 61 can adopt a conveyor belt mode and can also be arranged at an angle with respect to the horizontal plane as shown in Figure 10 to enable the fuse to slide down under the action of gravity. The material conveying mechanism 63 is arranged downstream of the feeding mechanism 61 and extends longitudinally. When continuously processing multiple fuses, in order to ensure that only one fuse enters the material conveying mechanism 63 at a time, a material distributing station 62 is provided between the feeding mechanism 61 and the material conveying mechanism 63.

[0046] The material distributing station 62 preferably includes an elastic stopper 621 and a downward pressing assembly 622 as shown in Figure 11 The downward pressing assembly 622 includes a downward pressing member and a downward pressing limiting member, and the downward pressing limiting member is used to limit the downward distance of the downward pressing member. The downward pressing member descends from the vertical upper side and presses against the fuse to be processed to align the fuses neatly and limit their further longitudinal displacement. The lower part of the elastic stopper 621 is supported by a spring. It is arranged in a slot formed on the bottom surface of the material distributing station 62 and vertically protrudes upward from the slot to block the fuse that will enter the material conveying mechanism 63. When the fuse that will enter the material conveying mechanism 63 has a tendency of longitudinal movement under the action of an external force, this fuse will squeeze the elastic stopper 621, and the spring supporting the elastic stopper 621 is compressed and may cause the elastic stopper 621 to tilt and partially enter the slot, so that the fuse crosses the elastic stopper 621 and enters the material conveying mechanism 63. After the fuse crosses the elastic stopper 621, the elastic stopper 621 returns to its original position under the action of the spring to block the next fuse.

[0047] The material conveying mechanism 63 is as shown in Figure 11 and 12As shown, it is configured to include a carrying platform 631, at least one supporting member 632, a fourth vertical displacement mechanism 633, and a first longitudinal displacement mechanism 634, wherein the number of the supporting members 632 is associated with the number of corresponding stations in the whole device. For example, when five stations, namely the material distribution station 62, the resistance detection station 1, the buffer station 5, the rotation station 2, and the sorting station 7 (detailed below) are adopted from upstream to downstream in this text, four corresponding supporting members 632 are required to transfer the fuses from the upstream stations to the downstream stations respectively. Specifically, the carrying platform 631 extends longitudinally and is provided with a vertically penetrating material transfer channel 635 longitudinally. The supporting member 632 can be displaced longitudinally in the material transfer channel 635 under the drive of the first longitudinal displacement mechanism 634, and each station is arranged at a corresponding position above the material transfer channel 635 vertically. A concave portion for accommodating the fuse is provided on the supporting member 632. The fourth vertical displacement mechanism 633 is used to drive the supporting member 632 to move vertically in the material transfer channel 635. When the supporting member 632 rises, it can hold up the fuse; when the supporting member 632 descends, the fuse will be lapped on the carrying platform 631 by means of its end cap or its contact blade, thereby releasing the fuse. During operation, the four supporting members 632 are first respectively located below the material distribution station 62, the resistance detection station 1, the buffer station 5, and the rotation station 2. The supporting member 632 rises vertically to hold up the fuse at the corresponding station, and then the supporting member 632 is displaced longitudinally in the direction of the next station, that is, they are respectively moved to below the resistance detection station 1, the buffer station 5, the rotation station 2, and the sorting station 7. The supporting member 632 descends to make the fuse fall onto the bearing platform, and finally the supporting member 632 resets back to the upstream station. Repeatedly executing the above steps realizes the synchronous displacement of the fuses at multiple stations.

[0048] In addition, only the preferred examples of the conveying device are given above, but the structure of the conveying device is by no means limited to this. For example, the whole conveying device can adopt the form of a conveyor belt, and determine the position of the fuse reaching each station by means of sensing and scanning. Or 4 corresponding manipulators can be respectively set, and each manipulator corresponds to the transfer of the fuse between an upstream station and a downstream station.

[0049] Figure 13The schematic diagram of the sorting device is shown. Since the above-mentioned resistance detection station 1 will send the measurement results to the controller, the controller will control the movement of the sorting device to separate the qualified and unqualified products. Specifically, the sorting device includes at least two sorting channels 71 arranged horizontally and a second horizontal displacement mechanism 72 that drives the sorting channels 71 to shift horizontally under the control of the controller. Different sorting channels 71 correspond to different collection containers 73. When, for example, a fuse that fails the resistance detection and has not been labeled appears, the second horizontal displacement mechanism 72 is activated to enable the fuse transferred from the rotary station 2 to enter a channel different from that of the qualified fuse, so as to enter a separate collection container 73. This approach does not need to interrupt the normal operation process of the entire device. Even if unqualified products in terms of resistance appear, it only needs to continue the transfer according to the set program, without manual intervention and without stopping the machine for processing.

[0050] The fuse testing and labeling equipment according to the present invention has changed the existing situation of manual operation in the existing production, not only ensuring the product quality, but also ensuring the consistency of labeling, accelerating the production speed and improving the production efficiency.
