[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] The first aspect of the present invention, as Figure 1-6 As shown, an energy storage welding blanking mechanism comprises: a blanking fixture 1, a first driving device 2 for driving the blanking fixture 1 to reciprocate, and a limiting device 3 for limiting the movement of the blanking fixture 1 between a loading position and a blanking position;

[0037] The blanking fixture 1 comprises a first transverse slide groove 11 and a second longitudinal slide groove 12 whose one end is connected to the middle of the first slide groove 11; a first baffle plate 111 and a second baffle plate 112 are provided at both ends of the first slide groove 11, and a first slider 113 and a second slider 114 are provided on the inner sides of the first baffle plate 111 and the second baffle plate 112, which are opposite to each other and can slide transversely in the first slide groove 11; a return spring 115 is provided between the first slider 113 and the first baffle plate 111, and between the second slider 114 and the second baffle plate 112, respectively, and the return spring 115 can return the first slider 113 and the second slider 114 to the middle of the first slide groove 11; symmetrical inwardly inclined inclined surfaces 116 are provided on the relative inner sides of the first slider 113 and the second slider 114;

[0038] A third slider 121 capable of longitudinally sliding in the second slide groove 12 is provided in the second slide groove 12, and a probe 122 for pushing the first slider 113 and the second slider 114 to both sides of the first slide groove 11 is provided at one end of the third slider 121 facing the first slide groove 11;

[0039] A slideway 13 for temporarily placing components is disposed on the upper surface of the blanking fixture 1 , and one end of the slideway 13 is connected to a blanking through hole 14 , and the position of the blanking through hole 14 corresponds to the middle of the first chute 11 .

[0040] Among them, the loading position refers to the position of the blanking fixture when the device is placed on the blanking fixture. When the blanking fixture is in this position, it cannot hinder the energy storage welder from performing welding operations; the blanking position corresponds to the welding position of the energy storage welding lower mold 4. The first driving device can be used as long as it can transport the blanking fixture to the loading position and the blanking position. Specifically, it can adopt but is not limited to linear motion, rotational motion and a combination of these motions. The blanking through-hole passes through the blanking fixture from top to bottom, and its position corresponds to the middle of the first slide groove, that is, the position corresponding to the inclined surfaces of the first and second sliders. The two relative inclined surfaces of the first slider and the second slider can support the device falling into the blanking through-hole when they are not pushed open. When the probe is pushed away from the blanking through-hole range, the blanking through-hole is opened, and the device falls out of the blanking fixture from the blanking through-hole. The slideway is in the shape of a groove. Since the sealing cap of the device is placed downward, the width and depth of the slideway only need to support and stably place the sealing cap of the device. The device can be placed on the slideway relatively easily (with the sealing cap facing downward), and then the device can be pushed into the blanking through hole along the slideway relatively easily. The action of pushing into the blanking through hole can be done manually (such as by hand or tweezers or a push plate), or by a device with a pushing function (such as a cylinder combined with a push plate), and the selection is made according to actual needs.

[0041] The process of this embodiment during actual operation is roughly as follows: first place the assembled device on the slide (with the sealing cap facing down), and then push the device along the slide into the blanking hole, and the device now stays on the two inclined surfaces of the first slider and the second slider; the first driving device moves the blanking fixture from the loading position to the blanking position, and pushes the third slider to move toward the first slide, and the probe pushes the first slider and the second slider to both sides of the first slide, and the device slides down along the two relative inclined surfaces of the first slider and the second slider. When the first slider and the second slider are pushed out of the range of the blanking hole, the device will fall to the welding position of the energy storage welding lower mold 4; after the device is blanked, the third slider is pushed back, and at this time the first and second sliders return to the initial position under the action of the reset spring; the first driving device returns the blanking fixture from the blanking position to the loading position, and at this time the energy storage welding device can perform welding operations, and this process can also be executed in a loop.

[0042] In this embodiment, a resettable slider is provided on the blanking fixture to support the device, and a movable probe is used to control whether the slider opens the blanking through hole, thereby realizing control over the blanking of the device. In conjunction with the movement of the blanking fixture between the loading position and the blanking position, the device can be very conveniently placed in the welding position of the energy storage welding lower mold 4, thereby solving the problem in the prior art that it is inconvenient to place the sealing cap and the base on the lower fixture, and the packaging efficiency is significantly improved.

[0043] As an optimized embodiment, Figure 3-4 As shown, the front end of the probe 122 is a conical structure, and the portions of the first slider 113 and the second slider 114 that contact the probe 122 are wedge structures.

[0044] In this embodiment, by cooperating with the conical structure of the probe and the wedge structure of the two sliders, the longitudinal extrusion of the probe can be converted into the lateral separation movement of the two sliders. When the probe is retracted, the two sliders can be reset under the action of the reset spring; thereby achieving the effect of controlling the opening and closing of the blanking hole by the movement of the probe.

[0045] In one embodiment, Figure 5-6 As shown, the output end of the first driving device 2 is connected to one end of the blanking fixture 1 through the motor bracket 21, and the limiting device 3 is provided with an arc-shaped limiting groove 31 with the connection between the first driving device 2 and the blanking fixture 1 as the center; the blanking fixture 1 is also provided with a limiting pin 32 that can slide in the limiting groove 31, and the blanking fixture 1 is in the blanking position when the limiting pin 32 slides to one end of the limiting groove 31, and the blanking fixture 1 is in the loading position when the limiting pin 32 slides to the other end of the limiting groove 31.

[0046] Among them, the first driving device can adopt a stepping motor. The limit groove on the clamp bracket cooperates with the limit pin on the blanking clamp to position the blanking clamp. The limit groove is arc-shaped, and the positions of its two ends correspond to the positions of the limit pin when the blanking clamp is in the loading position and the blanking position respectively. This embodiment realizes the switching of the loading position and the blanking position by using a rotational transposition method, which occupies a small space and the first driving device has a simple structure, and no additional connection mechanism is required.

[0047] In one embodiment, Figure 2 , 4 As shown, the first baffle plate 111 and the second baffle plate 112 are respectively provided with guide slide holes 117 , and the first slider 113 and the second slider 114 are provided with guide slide columns 118 on opposite outer sides thereof. The guide slide columns 118 pass through the guide slide holes 117 , and the return spring 115 is arranged on the guide slide columns 118 .

[0048] Among them, guide slide columns are arranged on the two sliders and are always placed in the guide slide holes on the baffle plate. The return spring is also arranged on the guide slide columns, which can better limit the two sliders to slide only along the length direction of the first slide groove, reduce the design and manufacturing requirements for the slide groove, and make the movement of the slider more stable.

[0049] In one embodiment, Figure 1-3 As shown, the blanking fixture 1 is further provided with a second driving device for driving the third slider 121 to reciprocate in the second slide groove 12 , and the output end of the second driving device is connected to the third slider 121 .

[0050] In this way, this embodiment can be used to further control the movement of the third slider. In particular, the second driving device can be implemented by a cylinder structure, that is, the second driving device includes a first cylinder and a first solenoid valve assembly for controlling the air intake and air outlet of the first cylinder, and the push end of the first cylinder is connected to the third slider.

[0051] The second aspect of the present invention, as Figure 7 As shown, an energy storage welding automatic blanking system includes the aforementioned energy storage welding blanking mechanism, and also includes a control unit 5, the control unit is respectively connected to the input ends of the first driving device and the second driving device;

[0052] The control unit is used to control the first driving device 2 to drive the blanking fixture 1 from the loading / blank position to the blanking / loading position; and is used to control the second driving device at the blanking position to drive the third slider 121 to be pushed out and retracted.

[0053] Among them, this embodiment can be implemented according to the following process during operation: control the first drive device to transport the blanking fixture from the loading position to the blanking position; control the second drive device to drive the third slider to be pushed out, open the blanking through hole so that the device falls to the position of the energy storage welding lower mold 4 due to its own weight; control the second drive device to drive the third slider to be retracted, close the blanking through hole; control the first drive device to transport the blanking fixture from the blanking position to the loading position. In this embodiment, the control unit controls the first and second drive devices to realize the automatic operation of the electronic device energy storage welding, and the energy storage welding efficiency is significantly improved.

[0054] In one embodiment, Figure 7 As shown, an energy storage welding automatic blanking system includes the aforementioned energy storage welding blanking mechanism, and also includes a control unit 5 and a sensor 6 connected to the control unit 5, wherein the control unit 5 is respectively connected to the input ends of the first driving device 2 and the second driving device;

[0055] The sensor 6 is used to detect whether there is a device in the blanking through hole 14, and if so, sends a device presence signal to the control unit 5;

[0056] The control unit 5 is used to receive the device existence signal and control the first drive device 2 to drive the blanking fixture 1 from the loading position to the blanking position; to control the second drive device to drive the third slider 121 to be pushed out and retracted at the blanking position; and to control the first drive device 2 to drive the blanking fixture 1 from the blanking position to the loading position after retracting the third slider 121.

[0057] Among them, there are multiple options for the sensor used to detect whether the device is present in the blanking through hole, which can be a contact sensor or an inductive sensor, which belongs to the prior art and will not be described in detail here. In this embodiment, by setting a sensor for detecting the device to control the driving of the blanking fixture, the automatic operation of the electronic device energy storage welding can be realized more efficiently, thereby improving production efficiency.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
