Description

Technical Field

[0001] The utility model relates to the technical field of battery production auxiliary equipment, and more specifically, to a welding head inspection tooling. Background Art

[0002] A lithium battery mainly consists of a housing, a wound core and an electrolyte, and most of the housings are made of aluminum. The lithium battery is in contact connection with the outside through positive and negative electrodes. During the battery production process, welding is required in multiple processes. When welding, it is necessary to inspect the welding head that plays a welding role. However, the end face of the welding head usually faces downwards. When inspecting the welding head, personnel need to bend down and look up to check the wear condition of the welding head, which does not meet the requirements of ergonomics.

[0003] Moreover, during the inspection process, in order to clearly view the wear condition of the welding head, it is also necessary to set up a light source for irradiation. However, when irradiating through an external light source in a small space below the end face of the welding head, shadows are easily generated, which is not conducive to viewing the welding head. Summary of the Utility Model

[0004] The utility model provides a welding head inspection tooling, which can very conveniently inspect the condition of the downward-facing end face of the welding head and meet the requirements of ergonomics.

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] A welding head inspection tooling includes:

[0007] A handle for hand-held grasping;

[0008] A housing, which is flat and connected to the handle;

[0009] A reflector, which is planar, located on the housing, and the mirror surface faces the outside of the housing. At the same time, the mirror surface of the reflector faces the same side as the flat surface where the housing is located;

[0010] A light source, which is located on the housing and is arranged around the center of the reflector. The irradiation direction of the light source and the mirror surface orientation of the reflector are on the same side; the light source is also electrically connected to a power supply.

[0011] For this welding head inspection tooling, the reflector is placed below the welding head, and the bottom state of the welding head is observed through the reflector. The light source emits light towards the bottom of the welding head, so as to quickly illuminate the bottom of the welding head to be observed in a small space. After the combination of the light source and the reflector, it is convenient to inspect the bottom of the welding head, meeting the requirements of ergonomics.

[0012] Preferably, the interior of the housing has a space for accommodating the reflector and the light source. One side of the housing has an opening for the mirror surface of the reflector to be exposed, and the housing is integrally formed, simplifying the formation method of the housing.

[0013] Preferably, the housing includes an upper housing and a lower housing; the light source and the reflector are installed in the lower housing, and an opening for the mirror surface of the reflector to be exposed is also provided on the upper housing. The housing is formed by combining the upper housing and the lower housing, which facilitates the installation of the light source and the reflector.

[0014] Preferably, the upper housing and the lower housing are connected together by means of pasting, magnetic attraction or clamping. Multiple methods are used to connect the upper housing and the lower housing to prevent them from separating from each other.

[0015] Preferably, the light source includes a plurality of lamp beads, and the lamp beads are arranged on a lamp board; the lamp board is fixedly installed on the bottom surface of the lower housing. A placement groove is provided at the center of the lamp board, and a reflector is installed in the placement groove. The lamp beads are arranged in an array around the center of the reflector; circular holes for the light of the lamp beads to irradiate are provided at corresponding positions on the upper housing. The plurality of lamp beads are arranged in an array around the center of the reflector, which is beneficial to reducing the influence of shadows on observing the soldering head.

[0016] Preferably, an anti-glare plate is detachably installed on the outer side of the upper housing; the anti-glare plate and the upper housing are connected by means of the cooperation of positioning posts and positioning holes. When the light of the lamp beads passes through the anti-glare plate, diffuse reflection occurs, which can provide brightness while preventing the light of the lamp beads from entering the eyes of the inspectors and causing glare, which is beneficial to protecting the inspectors and improving the universality of the device.

[0017] Preferably, an anti-glare plate is detachably installed on the outer side of the upper housing, and an anti-slip side plate is connected to the outer edge of the anti-glare plate. The anti-slip side plate is clamped on the outer side of the edge of the upper housing, enabling the anti-glare plate to rotate. Through holes corresponding to the positions of the circular holes are also provided on the anti-glare plate. The anti-glare plate is installed on the housing and can also rotate. During use, when a stronger light intensity is required, rotate the anti-slip side plate so that the circular hole and the through hole completely overlap, allowing the light emitted by the lamp beads to pass through the circular hole and the through hole. When other light intensities are required, rotate the anti-slip side plate to reduce the overlapping area between the through hole and the circular hole, and the light passing through the through hole by the lamp beads will also decrease accordingly. In this way, multi-level light intensity adjustment can be achieved according to needs, further enhancing the universality of the tooling.

[0018] Preferably, the handle and the housing are connected by a connecting rod made of TPU material. The TPU material has the characteristics of being bendable and shape-fixable. Users can bend the connecting rod according to specific needs to achieve various angles of observing the soldering head, which further facilitates observing the state of the bottom surface of the soldering head through the mirror.

[0019] Preferably, the inside of the handle is hollow for accommodating the power supply, and a switch is arranged at one end of the handle. Integrating the power supply into the handle can improve the overall appearance of the soldering head inspection tooling. Description of the Drawings

[0030] In the soldering head inspection tooling of this embodiment, the operator holds it through the handle 4, inserts the reflector 1 under the lower side of the soldering head end face, and the situation of the soldering head end face is reflected in the reflector 1, so as to conduct an inspection.

[0031] Specifically, as Figure 1 shown, a soldering head inspection tooling includes a handle 4, a housing 6, a reflector 1, a light source, and a power supply. The handle 4 is used for hand-held grasping; the housing 6 is flat and is connected to the handle 4; the reflector 1 is planar, located on the housing 6, and the mirror surface faces the outside of the housing 6. At the same time, the mirror surface of the reflector 1 faces the same side as the flat surface where the housing 6 is located; the light source is located on the housing 6 and is arranged around the center of the reflector 1, and the irradiation direction of the light source is on the same side as the mirror surface orientation of the reflector 1; the light source is also electrically connected to the power supply.

[0032] In this embodiment, the housing 6 is in the shape of a flat disc and has a space for accommodating the reflector 1 and the light source inside. The so-called "flat shape" is only approximately flat and does not strictly limit it to having two flat planes. In some cases, the flat surface of the housing 6 may be a flat arc, as long as the housing 6 can hold the reflector 1 and the light source and enter the space below the soldering head end face.

[0033] In other embodiments, the housing 6 is not in the shape of a shell and can also be a flat support body. The reflector 1 is arranged on the support body, and the light source is arranged around the outer edge of the reflector 1. In this embodiment, for the convenience of understanding, it is described as the housing 6.

[0034] In this embodiment, during use, the reflector 1 is placed below the end face of the welding head. The state of the end face below the welding head is observed through the reflector 1. The light source emits light towards the bottom of the welding head. The light source and the reflector 1 are combined to quickly illuminate the bottom of the welding head that needs to be observed in a small space, which helps to avoid using an external light source for illumination. For example, when using a flashlight, the light of the flashlight is easily blocked by other mechanisms. After the light source and the reflector 1 are combined in this embodiment, it is convenient to inspect the bottom of the welding head.

[0035] In one case, the interior of the housing 6 has a space for accommodating the reflector 1 and the light source. One side of the housing 6 has an opening for the mirror surface of the reflector 1 to be exposed, and the housing 6 of the shell is integrally formed. In this case, the housing 6 is made of elastic silicone or rubber material, and the housing 6 forms an integral structure. The light source can be installed into the housing 6 through the deformation of the housing 6.

[0036] In this embodiment, combined with Figure 2 As shown, the housing 6 is made of a hard material. The housing 6 includes an upper housing and a lower housing. The light source and the reflector 1 are installed in the lower housing. An opening for the mirror surface of the reflector 1 to be exposed is also provided on the upper housing. The upper housing and the lower housing are connected together by a snap-fit method. Connecting structures that can be snap-connected to each other are provided on the upper housing and the lower housing to snap them together. In other cases, the upper housing and the lower housing can also be connected by pasting or magnetic attraction.

[0037] Combined with Figure 3 As shown, in this embodiment, the light source includes a plurality of lamp beads 7. The lamp beads 7 are arranged on the lamp board 2. The lamp board 2 is fixedly installed on the bottom surface of the lower housing. Specifically, the lamp board 2 is in a disc shape. The outer side of the lamp board 2 has a mounting disc. An installation groove 10 is provided on the bottom surface of the lower housing. The mounting disc of the lamp board 2 is located in the installation groove 10. A placement groove 13 is provided at the center of the lamp board 2. The position of the placement groove 13 corresponds to the position of the opening on the upper housing. The reflector 1 is installed in the placement groove 13, and the lamp beads 7 are arranged in an array around the center of the reflector 1. The lamp beads 7 are located on the mounting disc of the lamp board 2. A plurality of lamp beads 7 helps to reduce the influence of shadows on observing the welding head. For example, the number of lamp beads 7 is set to three, and the lamp beads 7 are evenly distributed. In some cases, the light source can also be a circular light belt, which is arranged around the reflector 1.

[0038] In this embodiment, the reflector 1 is an integral structure and is made of a glass mirror. The lamp beads 7 are arranged in an array around the center of the reflector 1 and are located outside the reflector 1. Installing the lamp beads 7 in the middle of the reflector 1 will damage the integrity of the welding head in the mirror surface and affect the inspection of the welding head.

[0039] In other embodiments, the reflector 1 can also be a metal mirror made of a metal material. Compared with a glass mirror, a metal mirror made of a metal material with a shiny surface effect has better drop resistance.

[0040] In this embodiment, a round hole for the light irradiation of the lamp bead 7 is opened at the corresponding position on the upper shell, and the light emitted by the lamp bead 7 irradiates outward through the round hole.

[0041] The handle 4 and the outer shell 6 are connected by a connecting rod 3. In this embodiment, the connecting rod 3 is made of TPU material. The TPU material has the characteristics of being bendable and shapeable. The user can bend the connecting rod 3 according to specific needs to achieve observing the soldering head at various angles, which further facilitates observing the state of the bottom surface of the soldering head through the reflector 1. Of course, in other embodiments, the connecting rod 3 can also be made of other materials.

[0042] In this embodiment, the inside of the handle 4 is hollow for accommodating the power source, and a switch 5 is provided at one end of the handle 4. The inside of the connecting rod 3 has a hollow structure, and a wire groove 8 is opened at the connection between the outer shell 6 and the connecting rod 3. The power source is located in the hollow cavity inside the handle 4, the light source is located on the outer shell 6, and the power source is electrically connected to the light source through a wire. The wire enters the outer shell 6 through the inside of the connecting rod 3 and the wire groove 8 and is connected to the light source.

[0043] The power source is a battery, and its connection with the light source can be controlled by the switch 5. In some cases, the battery is a rechargeable battery. For the convenience of charging, a charging port is provided at one end of the handle 4. The charging port and the switch 5 are on the same side, and a detachable dust-proof block is also provided at the charging port to prevent dust from entering the charging port.

[0044] Combined Figure 2 and Figure 3 As shown, in a preferred embodiment, a plurality of first positioning posts 11 are fixedly provided on the bottom inner wall of the lower shell of the outer shell 6, and first positioning holes 14 adapted to the first positioning posts 11 are opened on the lamp board 2. The first positioning posts 11 are correspondingly inserted into the first positioning holes 14 to prevent the lamp board 2 from having a relative rotational position offset in the outer shell 6, which is beneficial to keeping the light emitted by the lamp bead 7 passing through the round hole.

[0045] After the lamp board 2 provided with the lamp bead 7 is installed on the lower shell, the reflector 1 is arranged in the placement groove 13, and the upper shell and the lower shell are buckled together. The upper shell is attached to the mounting plate of the lamp board 2, and at the same time, the inner edge of the opening of the upper shell presses on the outer edge of the reflector 1 to fix the reflector 1 through the upper shell.

[0046] As a further improvement, in this embodiment, an anti-glare plate 16 is detachably installed on the outside of the upper shell. When the light of the lamp bead 7 passes through the anti-glare plate 16, diffuse reflection occurs, which can avoid the light of the lamp bead 7 from entering the eyes of the inspection personnel and causing glare while providing brightness, which is beneficial to protecting the inspection personnel and improving the universality of the device.

[0047] Such as Figure 4As shown in the figure, in this embodiment, the anti-glare plate 16 and the upper housing are connected by means of the cooperation of positioning posts and positioning holes. Specifically, a number of second positioning holes 12 are provided on the upper housing in the outer housing 6 and on the mounting plate in the lamp board 2. The bottom of the anti-glare plate 16 is provided with second positioning posts 15 adapted to the second positioning holes 12. After the second positioning holes 1 and the second positioning posts 15 are fitted and installed, a frictional force is generated between the inner wall of the second positioning hole 12 and the surface of the second positioning post 15, preventing the anti-glare plate 16 from falling off the outer housing 6. At this time, the anti-glare plate 16 and the outer housing 6 are of a detachable structure, and in some usage cases, the anti-glare plate 16 can also be removed to check the welding head. In other cases, the second positioning holes 12 can also be provided only on the upper housing, or positioning posts can be provided on the upper housing and positioning holes can be provided on the anti-glare plate 16.

[0048] As Figure 5 shown, in another embodiment, the outer edge of the anti-glare plate 16 is connected to an anti-slip side plate 17, and the anti-slip side plate 17 is snap-fitted outside the edge of the upper housing, enabling the anti-glare plate 16 to rotate. A through hole 9 corresponding to the position of the round hole is also provided on the anti-glare plate 16. Specifically, there is a frictional force between the inner wall of the anti-slip side plate 17 and the outer wall of the upper housing. At this time, the anti-glare plate 16 with the anti-slip side plate 17 forms a plug-in relationship with the outer housing 6, installing the anti-glare plate 16 on the outer housing 6 and enabling the anti-glare plate 16 to rotate at the same time. When in use, when a stronger light intensity is required, the anti-slip side plate 17 is rotated so that the round hole and the through hole 9 completely overlap, allowing the light emitted by the lamp beads 7 to pass through the round hole and the through hole 9. When other light intensities are required, the anti-slip side plate 17 is rotated, and the overlapping area between the through hole 9 and the round hole is reduced, and the light passing through the through hole 9 by the lamp beads 7 will also decrease accordingly until there is no overlapping area between the through hole 9 and the round hole. In this way, multi-level light intensity adjustment can be realized according to requirements, further enhancing the universality of this tooling.

[0049] In the welding head inspection tooling of this embodiment, the reflector 1 is placed below the end face of the welding head to be inspected, and the state of the bottom end face of the welding head is observed through the reflector 1. The switch 5 is pressed, and the lamp beads 7 on the lamp board 2 emit light towards the bottom of the welding head, thereby realizing rapid lighting of the bottom of the welding head to be observed in a small space. After the lamp beads 7 and the reflector 1 are combined, it is convenient to inspect the bottom of the welding head, meeting the requirements of ergonomics.
