Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

An embodiment of a nail pulling apparatus and a nail pulling machine according to the present utility model will be described in further detail with reference to the accompanying drawings.

In one aspect, as shown in fig. 1 and 2, the present utility model provides a nail pull detection apparatus comprising a support frame 6 for positioning below a nail pick-up assembly 9, a weigh bin 1 and a weight sensor 3. The weighing box 1 is placed on the supporting frame 6, and the removed glue nails are collected, and whether the glue nails of one battery module are completely removed is judged by weighing all the glue nails removed by the battery module.

It will be appreciated that since the mass and size of each staple is almost the same, the number of staples can be determined by detecting the weight. For example, when the nails are not removed or broken nails occur when the nails are removed, the weight of the nails removed at this time and falling into the weighing box 1 is smaller than the set weight, so that it can be judged that some of the nails are not removed or broken nails occur.

In some alternative embodiments, the nail pull detection apparatus further comprises a detection control mechanism and is in signal connection with the weight sensor 3. When the weight sensor 3 measures the weight of the glue nail in the weighing box 1 and feeds back the weight to the detection control mechanism, and the detection control mechanism judges that the weight value cannot reach the set weight value, the nail taking assembly 9 is controlled to re-pull the battery module again.

Of course, a smaller range interval can be selected for the set weight value, so that the problem of low nail pulling efficiency caused by invalid re-pulling caused by errors is solved.

In some alternative embodiments, the nail pull detection apparatus further includes a driving member 2, the weigh bin 1 includes a frame 11 and a bottom plate 12, the bottom plate 12 is slidably connected to the frame 11, and the driving member 2 is connected to the bottom plate 12, so as to close or open the bottom plate 12 to the frame 11.

It will be appreciated that the direction of movement of the output end of the driving member 2 is the same as the direction of sliding connection of the base plate 12 with the frame 11. In this example, the driving member 2 is a rodless cylinder, and a slider of the rodless cylinder is connected to a stopper extending from the bottom plate 12. When the slide block of the rodless cylinder reciprocates, the bottom plate 12 can slide relative to the frame 11, so that the frame 11 is opened or closed, and the glue nails collected in the frame 11 fall.

In some alternative embodiments, the base plate 12 is hinged to the bottom of the frame 11, and the driving member 2 is a rodless cylinder, and a sliding direction of a slider of the rodless cylinder is perpendicular to a rotating direction of the base plate 12 with respect to the frame 11, so that the base plate 12 opens or closes the frame 11 when the slider reciprocates. When the bottom plate 12 closes the frame 11, the sliding block of the rodless cylinder abuts against the bottom surface of the bottom plate 12, so that the bottom plate 12 completely closes the bottom of the frame 11, and the glue nails in the weighing box are prevented from falling off.

In the above embodiment, a rodless cylinder is preferably provided at both ends of the weighing cell 1 to better enable the bottom plate 12 to close the frame 11 and support the bottom plate 12.

In some alternative embodiments, the nail pull detection apparatus further comprises a picking assembly 4 for moving the weighing box 1 on the support frame 6 out below the nail picking assembly 9.

Specifically, the box taking assembly 4 includes a box taking plate 41 and a box taking driving member 42, the box taking plate 41 is used for supporting the weighing box 1, and the box taking driving member 42 is connected with the box taking plate 41 and is used for driving the box taking plate 41 to displace along the vertical direction and the horizontal direction.

The purpose of setting up and getting box subassembly 4 is, get nail subassembly 9 and carry out the back to the battery module, and when the gluey nail weight in the box 1 of weighing still can not reach the settlement weight, gets box driving piece 42 then control and gets box board 41 and remove to the below of box 1 of weighing this moment to move up and make it leave support frame 6 with bearing box 1 of weighing, and will weigh box 1 and shift out the below of getting nail subassembly 9. Therefore, the glue nails with abnormal nail pulling can be manually subjected to further screening inspection to determine the condition of missing or broken nails, meanwhile, broken nails are selected, and other glue nails without problems are collected for recycling.

In this example, to cooperate with the above-mentioned nail taking assembly 9, the supporting frame 6 includes two supporting bases 61 and two sets of limiting baffle groups arranged at intervals, each set of limiting baffle groups includes two limiting baffles 62 arranged at intervals, and the weighing box 1 is placed on the two supporting bases 61 and is clamped between the two limiting baffles 62 of each set. It should be noted that, the distance between the two supporting bases 61 should be satisfied, so that the box taking plate 41 may be located between the two supporting bases 61 to support the weighing box 1 and lift the weighing box 1 upwards, so that the weighing box 1 is no longer clamped between the two limiting baffles 62. In this example, two support bases 61 are respectively located at two ends of the weighing box 1 in the length direction, two sets of limit baffles are also located at two ends of the weighing box 1 in the length direction, and two limit baffles 62 in each set are respectively located at two sides of the weighing box 1 perpendicular to the length direction.

Optionally, the weight sensor 3 is mounted on a support base 61.

When the bottom plate 12 of the weighing box 1 is slidably arranged at the bottom of the frame 11, the two limit baffles 62 are clamped on two sides of the frame 11 along the sliding direction of the bottom plate 12, so that the movement of the frame 11 caused when the driving piece 2 slides the bottom plate 12 is avoided.

Of course, in other embodiments, the staple taking assembly 9 may be a robotic arm or the like, by which the weigh cartridge 1 is grasped and moved out under the staple taking assembly 9.

In some alternative embodiments, the box-taking driving part 42 includes a first cylinder 421 and a second cylinder 422, where an output end of the first cylinder 421 is retractable in a horizontal direction; the second cylinder 422 is connected to the output end of the first cylinder 421, and the output end of the second cylinder 422 is connected to the box taking plate 41 and is retractable in the vertical direction.

It will be appreciated that when the weighing box 1 needs to be taken away from the support frame 6, the output end of the second air cylinder 422 extends downwards to drive the box taking plate 41 to move downwards until the top surface of the box taking plate 41 is lower than the bottom surface of the weighing box 1, then the output end of the first air cylinder 421 extends towards the direction close to the weighing box 1 to drive the box taking plate 41 to move towards the weighing box 1, and when the first air cylinder 421 and the second air cylinder 422 both travel in place, the box taking plate 41 is located under the weighing box 1. At this time, the output end of the second cylinder 422 is retracted upwards again to move the box taking plate 41 upwards towards the weighing box 1 until the weighing box 1 is supported by the box taking plate 41, and then the output end of the first cylinder 421 is retracted horizontally again, so that the box taking plate 41 drives the weighing box 1 to move out of the supporting frame 6.

In this example, since the supporting base 61 and the limiting baffle 62 are provided, the output end of the second air cylinder 422 needs to retract upward to enable the box taking plate 41 to drive the weighing box 1 to move upward until the limiting baffle 62 no longer clamps the weighing box 1, and then the output end of the first air cylinder 421 retracts horizontally again to enable the box taking plate 41 to drive the weighing box 1 to move out of the supporting frame 6.

In some alternative embodiments, the box-taking plate 41 is provided with a box-taking positioning block 411 and a box-taking sensor 412, and the box-taking sensor 412 is in signal connection with the box-taking driving member 42.

In this example, four box taking positioning blocks 411 are provided, and are respectively located on four top corners of the rectangle of the box taking plate 41, and the four box taking positioning blocks 411 can clamp and position the weighing box 1 on the box taking plate 41. The box taking sensor 412 is a correlation sensor, and is used for sensing whether the weighing box 1 is located in the area between the four box taking positioning blocks 411.

Specifically, the box taking positioning block 411 is used for positioning the relative position of the weighing box 1 on the box taking plate 41, so as to avoid the problem that the weighing box 1 falls off in the process of moving the weighing box 1. When the box taking sensor 412 senses that the weighing box 1 is located in the area between the four box taking positioning blocks 411, a command is sent to enable the box taking driving piece 42 to be recovered, so that the weighing box 1 is separated from the supporting frame 6.

In some alternative embodiments, the nail pull detection apparatus further comprises a box feeding assembly 5 for moving the weighing box 1 onto the support frame 6.

Specifically, the box feeding assembly 5 includes a box feeding plate 51 and a box feeding driving member 52, wherein the box feeding plate 51 is used for placing the weighing box 1; a cassette feeding driving member 52 is coupled to the cassette feeding plate 51 for driving the cassette feeding plate 51 to displace in the vertical and horizontal directions.

The purpose of setting up send box subassembly 5 is, after getting box subassembly 4 will be equipped with the weighing box 1 of unusual glue nail and shift out support frame 6, in order not to influence continuous production this moment, improves nail pulling efficiency, needs place empty weighing box 1 on support frame 6. The empty weighing cell 1 placed on the cell plate 51 is thus moved by the cell drive 52 and placed on the support frame 6.

Of course, the box feeding assembly 5 may start to work when the weighing box 1 is not placed on the supporting frame 6, and is not limited to the box taking assembly 4 taking the weighing box 1.

In some alternative embodiments, the box feeding driving member 52 includes a third cylinder 521 and a fourth cylinder 522, and an output end of the third cylinder 521 may be extended and contracted in a horizontal direction; a fourth cylinder 522 is connected to an output end of the third cylinder 521, and an output end of the fourth cylinder 522 is connected to the box feeding plate 51 and is vertically extendable.

It can be understood that, in this example, when the weighing box 1 needs to be moved onto the support frame 6, the output end of the fourth cylinder 522 is moved up to a specified travel height, so as to drive the box feeding plate 51 to move up until the bottom surface of the box feeding plate 51 moves to the top surface of the support frame 6, then the output end of the third cylinder 521 extends towards a direction close to the support frame 6, so that the box feeding plate 51 supports the weighing box 1 to move towards the support frame 6, after the third cylinder 521 and the fourth cylinder 522 are all in place, the weighing box 1 is placed on the support frame 6, and the box feeding plate 51 does not support the weighing box 1 any more, at this time, the output end of the third cylinder 521 horizontally retracts towards a direction far from the support frame 6, so as to complete the box feeding action.

In this example, since the support base 61 and the limit baffle 62 are provided, when the output end of the fourth cylinder 522 is up to the specified stroke height, the bottom surface of the box feeding plate 51 should be higher than the top surface of the limit baffle 62, so that the limit baffle 62 can clamp the weighing box 1 when the weighing box 1 is driven to move down until the support base 61 is reached.

In some alternative embodiments, the box feeding plate 51 is provided with a box feeding positioning block 511 and a box feeding sensor 512, and the box feeding sensor 512 is in signal connection with the box feeding driving member 52.

In this example, four box feeding positioning blocks 511 are provided and are respectively located at four top corners of the rectangle of the box feeding plate 51, and the four box feeding positioning blocks 511 can clamp and position the weighing box 1 on the box feeding plate 51. The case feeding sensor 512 is a correlation sensor for sensing whether the weighing case 1 is located in the area between the four case feeding positioning blocks 511.

Specifically, the box feeding positioning block 511 is used for positioning the relative position of the weighing box 1 on the box feeding plate 51, so as to avoid the problem that the weighing box 1 falls off during the process of moving the weighing box 1. When the box feeding sensor 512 senses that the weighing box 1 is no longer located in the area between the four box feeding positioning blocks 511, a command is sent to enable the box feeding driving piece 52 to be recovered, and the box feeding plate 51 is enabled to be separated from the supporting frame 6 to return to the initial position.

It should be noted that, by the box taking assembly 4 and the box feeding assembly 5, the weighing box with the abnormal glue nail is removed from the supporting frame 6, and a new weighing box is placed. The weighing boxes are the same in size and identical in structure. In order to ensure that each weighing box 1 can be matched with the driving piece 2 to open the bottom plate 12 of the weighing box 1, all the removed nails of one battery module fall into the collecting device so as to weigh the nails after the next battery module is removed, therefore, when each weighing box 1 is placed on the two supporting bases 61 of the supporting frame 6 and clamped with the limiting baffle plates 62, the stop blocks extending from the bottom plate 12 of the weighing box 1 are detachably connected with the sliding blocks of the driving piece 2. For example, the slider of the driving member 2 is actuated to make a reciprocating motion each time, namely, the bottom plate 12 of the weighing box 1 is opened to drop the glue nails, then the bottom plate 12 of the weighing box 1 is closed, and the slider returns to the initial position. Therefore, when the weighing box 1 is placed on the support frame 6, the stop block extending from the bottom plate 12 is clamped in the groove formed in the top surface of the sliding block of the driving piece 2, so that the driving piece 2 is conveniently and detachably connected with the bottom plate 12 when the weighing box 1 is taken away from or placed on the support frame 6.

In some alternative embodiments, as shown in fig. 3, the nail pulling detecting device further includes a collecting box 10, which is located below the weighing box 1, and is used for collecting the dropped nails when the bottom plate of the weighing box 1 is opened.

It will be appreciated that when the weight sensor 3 measures that the weight of the glue in the weighing box 1 meets the requirements, the driving member 2 is operated to open the bottom plate 12, and the glue in the box falls into the collecting box 10, so that the glue can be reused after being collected.

Preferably, detection means are provided on the cartridge 10 for alerting when the nails in the cartridge 10 reach a set number, so as to facilitate the replacement of a new cartridge 10.

In this example, a through hole is formed in the side wall of the collection box 10 near the top, a light sensor 101 is arranged at the through hole and is in signal connection with an alarm system of the control center, and when the glue nail fills the collection box 10 until reaching the through hole and triggers the light sensor 101, the control center gives an alarm.

Optionally, the light sensor 101 may also be signally connected to a switch of the nailer to stop the nailer when the collection magazine 10 is full.

On the other hand, the utility model also provides a nail pulling machine, which comprises the nail pulling detection device.

Specifically, the nail pulling machine comprises a nail taking assembly 9, a supporting frame 6, a weighing box 1 and a weight sensor 3. The support frame 6 is placed in the below of getting nail subassembly 9, and weighing box 1 is placed on support frame 6 to collect and pull out the glued nail of whereabouts from getting nail subassembly 9, through weighing all glued nails that a battery module was pulled out, judge whether pull out completely the glued nail of this battery module.

As shown in fig. 4 and 5, the battery module 7 is placed in the battery tray, and is moved to the lower side of the nail taking assembly 9 of the nail puller by the roller 81 of the feeding mechanism 8, and at this time, the battery tray is guided and limited by the side guide bar 82 and the limit stop 83 of the feeding mechanism 8, so that the battery tray reaches the set position. When the in-place sensor 84 senses that the battery tray reaches the set position, the positioning cylinder 85 enables the positioning pin 87 above the supporting plate 86 to extend and be clamped with the limiting groove at the bottom of the battery tray, so that the relative position of the battery tray on the feeding mechanism 8 is fixed. Because the battery tray is accurately positioned below the nail taking assembly 9 at this moment, the nail taking assembly 9 can move to the upper side of the battery tray, the battery module on the battery tray is taken by the clamping jaw, after the nail taking is completed, the nail taking assembly 9 grabs the pulled-out glue nail, the nail taking assembly moves to the position where the glue nail is collected by the truss robot 91, the clamping jaw is loosened, the pulled-out glue nail falls into the glue nail recycling mechanism, and the nail pulling process for one battery module is completed.

At this time, if the glue nails of one battery module are completely pulled out, the weights of all the glue nails pulled out and fallen into the weighing box 1 meet the set weight; if the glue nails are not pulled out or broken nails appear during pulling out, the weight of the glue nails which are pulled out and fall into the weighing box 1 at the moment is smaller than the set weight. So that it is possible to detect whether all the nails of the battery module are completely removed.

Preferably, as shown in fig. 6, the nail extractor has all the functions that a single machine should have, such as: the top of the device is provided with a tri-colored lamp 001 for indicating the state of the device; a display screen 002 to display the device status; manual automatic switch button 003; a reset button 004; a scram switch 005; pause switch 006. When the equipment door is opened, the equipment automatically alarms and stops the current action, and the action before the door is opened is continued after the equipment door is closed. The upper part of the equipment is provided with a main control system, a PLC, a cylinder control valve, an electric roller and an electromagnetic valve; the power supply and the main jacking mechanism are arranged below the equipment.

If the weight of the glue nail in the weighing box 1 is within the allowable error range of the set weight, the situation that the glue nail is pulled out is indicated to be complete, the driving piece 2 drives the bottom plate 12 to slide relative to the frame 11 so that the glue nail falls into the collecting box 10, and then the driving piece 2 returns to the initial position so that the bottom plate 12 seals the frame 11, and preparation is made for the detection of the pulling out of the next battery module. If the weight of the glue nail in the weighing box 1 is smaller than the set weight, it can be determined that some glue nails are not pulled out or broken nails exist, the nail taking assembly 9 re-pulls the battery module again, and when the weight of the glue nail in the weighing box 1 still does not meet the set weight after re-pulling, the box taking driving piece 42 controls the box taking plate 41 to move to the lower side of the weighing box 1, and moves upwards to support the weighing box 1 to leave the supporting frame 6, and moves the weighing box 1 out of the lower side of the nail taking assembly 9. Therefore, the glue nails with abnormal nail pulling can be further screened and checked manually to determine the condition of missing nail pulling or broken nails, broken nails are selected at the same time, and other glue nails without problems are collected for recycling; after the weighing box 1 with the abnormal glue nails is moved out of the supporting frame 6 by the box taking assembly 4, the empty weighing box 1 placed on the box feeding plate 51 is moved and placed on the supporting frame 6 by the box feeding driving piece 52, so that continuous production is not affected, and the nail pulling efficiency is improved. The glue nail in the weighing box 1 falls into the collecting box 10, and when the glue nail fills the collecting box 10 until reaching the through hole, and the light sensor 101 is triggered, the control center gives an alarm, so that a new collecting box 10 is replaced.

According to the nail pulling detection device and the nail pulling machine, the extracted nails on each battery module are weighed to detect whether the extracted nails are in set weight or not, and whether the extracted nails are in place or not is determined; the bottom plate of the weighing box is arranged to be openable and closable, so that the detection of the glue nails of each battery module is facilitated; through setting up and getting the box subassembly, can remove the support frame with the weighing box that is equipped with unusual glue nail, confirm and pick out unusual glue nail by hand, be convenient for collect non-unusual glue nail; by arranging the box feeding assembly, when abnormal glue nails are selected manually, a box feeding house can place a new weighing box on the support frame, and the nail puller can work continuously to improve the nail pulling efficiency; by collecting the glue nails falling from the weighing box in the collecting box, the glue nails which are not abnormal can be collected for recycling.
