Description

Technical Field

[0001] The present invention relates to the technical field of heat-sealing positioning, and in particular, to a device for heat-sealing positioning of a cover sheet with repeatable positioning accuracy. Background Technology

[0002] The heat sealing process is one of the main methods for lead-acid battery cover. The difficulty of heat sealing is that the surface sheet can only be positioned around the surface sheet during heat sealing. However, after the heat sealing is completed, the surface sheet needs to be completely pressed into the battery cover. At this time, the positioning structure will interfere with the battery cover, causing the surface sheet to not be pressed to the bottom, crushing the battery cover, etc. Therefore, the traditional surface sheet heat sealing and cover lifting mechanism does not have a positioning structure, resulting in a high defect rate of misalignment between the surface sheet and the battery cover during heat sealing.

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made with reference to the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0036] Refer to Figures 1 to 3 , the first embodiment of the device for heat-sealing and positioning the noodle sheet of the present invention. The main body of this embodiment includes a fixing component 100 and a positioning component 200. The fixing component 100 is divided into a first surface A, a second surface B and a third surface M. Among them, the third surface M is partially recessed from the first surface A towards the second surface B, so that the fixing component 100 is in an "E" shape. The so-called "partial" here refers to a partial area on the third surface M, and the recessed areas are spaced on the first surface A. Refer to Figures 1 to 3The fixed component 100 therein has a "E" shape formed by a partial interval depression on the first surface A, and the depressed surfaces are all in the same plane, which is the third surface M. A positioning hole 101 is provided on the first surface A, and the positioning hole 101 penetrates through the fixed component 100.

[0037] When performing the hot covering process on the cover sheet of a lead-acid battery, the difficulty of the hot covering process lies in that during hot covering, only the periphery of the sheet can be positioned. However, after the hot covering is completed, the sheet needs to be completely pressed into the battery cover. At this time, the positioning structure will interfere with the battery cover, resulting in defects such as the sheet not being pressed to the bottom or damaging the battery cover. Therefore, traditional sheet hot covering and lid lifting mechanisms do not have a positioning structure, resulting in a relatively high defect rate of misalignment between the sheet and the battery cover during hot covering. Therefore, in this embodiment, a positioning component 200 is provided. The positioning component 200 is placed in the positioning hole 101 and cooperates with the positioning hole 101. The positioning component 200 includes a positioning post 201. Refer to Figure 5 , the positioning post 201 includes a contact portion 201a and a limiting portion 201b. In the initial state, the positioning post 201 is inserted into the positioning hole 101 and cooperates with the positioning hole 101. At this time, the contact portion 201a protrudes from the surface of the second surface B. When covering the cover sheet of the lead-acid battery (i.e., refer to Figure 1 or Figure 4 ), the contact portion 201a contacts the sheet, and the positioning post 201 expands and contracts vertically, effectively positioning the sheet, preventing misalignment between the sheet and the battery cover during hot covering, and not interfering with the battery cover at the same time.

[0038] Preferably, the positioning hole 101 is a stepped hole, and a fourth surface a is provided inside it. The fourth surface a is formed by cutting a circle with a first radius from the first surface A towards the second surface B without cutting to the second surface B. The fourth surface a contacts the limiting portion 201b to limit the positioning post 201. It should be noted that the radius of the hole of the positioning hole 101 is divided into a first radius and a second radius. Among them, a circle with the first radius is cut from the first surface A to the fourth surface a, and then a circle with the second radius is continuously cut from the fourth surface a to the second surface B. It should be noted that the height of the positioning post 201 is greater than the distance between the fourth surface a and the second surface B, so that when the limiting portion 201b of the positioning post 201 contacts the fourth surface a, the contact portion 201a of the positioning post 201 can protrude from the surface of the second surface B.

[0039] Refer to Figure 2 and Figure 4, the difference between the second embodiment of the present invention and the first embodiment is that: the main body of the device includes a fixing component 100 and a positioning component 200. The positioning component 200 further includes a resetting member 202. The resetting member 202 is placed above the positioning post 201, so that when the positioning post 201 is placed on the fourth surface a, the abutting portion 201a can protrude from the surface of the second surface B. When the abutting portion 201a of the positioning post 201 abuts against the patch, the positioning post 201 moves upward (i.e., from the second surface B to the first surface A direction) until the abutting portion 201a retracts into the positioning hole 101. When the abutting portion 201a leaves the patch again, under the action of the resetting member 202, the abutting portion 201a still protrudes from the surface of the second surface B.

[0040] In this embodiment, the resetting member 202 is made of brass as a counterweight and is placed above the positioning post 201 from the positioning hole 101 at the first surface A end. The counterweight is made of brass with a relatively large density. Its function is to apply a suitable pressure to the positioning post 201 to ensure that the positioning post 201 is in the "extended" state before pressing the battery cover, effectively positioning the patch. When the positioning post 201 presses the battery cover during heat sealing, it ensures that the positioning post can "retract" with a small force without damaging the battery cover. The pressure of the counterweight structure is moderate and the structure is simple.

[0041] Specifically, the fixing component 100 is divided into a first surface A, a second surface B and a third surface M. Among them, the third surface M is partially recessed from the first surface A to the second surface B, so that the fixing component 100 is in an "E" shape. The "partial" here refers to a partial area on the third surface M, and the recessed areas are spaced on the first surface A. Refer to Figures 1 to 3 the fixing component 100 in, the first surface A is partially and spacedly recessed to form an "E" shape, and the recessed surfaces are all in the same plane, which is the third surface M. The first surface A is provided with a positioning hole 101, and the positioning hole 101 penetrates the fixing component 100. Among them, the positioning hole 101 is a stepped hole, and a fourth surface a is provided inside it. The fourth surface a is formed by cutting from the first surface A in a circle with a first radius towards the second surface B without cutting to the second surface B.

[0042] The positioning component 200 is placed in the positioning hole 101 and cooperates with the positioning hole 101. The positioning component 200 includes a positioning post 201. Refer to Figure 5 , the positioning post 201 includes an abutting portion 201a and a limiting portion 201b. In the initial state, the positioning post 201 is inserted into the positioning hole 101 and cooperates with the positioning hole 101. At this time, the abutting portion 201a protrudes from the surface of the second surface B. When sealing the patch of the lead-acid battery (i.e., refer to Figure 1 or Figure 4 ), the abutting portion 201a abuts against the patch, and the positioning post 201 vertically expands and contracts, effectively positioning the patch, preventing the patch from being misaligned with the battery cover during heat sealing, and not interfering with the battery cover at the same time.

[0043] The positioning post 201 and the positioning hole 101 are designed with a relatively long mating distance and adopt an E8 / h7 tolerance fit to ensure a reasonable clearance. The positioning post can slide freely in the mounting hole without wobbling. When positioning the patch, the position deviation of the patch can be ensured to be less than 0.15 mm.

[0044] In this embodiment, the reset member 202 is preferably made of brass as a counterweight, which is placed from the positioning hole 101 at the A end of the first surface and placed above the positioning post 201. The counterweight is made of brass with a relatively large density. Its function is to apply a suitable pressure to the positioning post 201 to ensure that the positioning post 201 is in the "extended" state before pressing on the battery cover, effectively positioning the patch. When the positioning post 201 presses on the battery cover during heat sealing, it ensures that the positioning post can "retract" with a relatively small force without damaging the battery cover. The structure of the counterweight has a moderate pressure and a simple structure.

[0045] For the third embodiment of the device for thermally sealing and positioning the patch of the present invention, the difference between this embodiment and the second embodiment is that: the reset member 202 adopts an elastic member, one end of which is connected to the positioning post 201 and the other end is connected to the fixing component 100. It should be noted that the elastic member can be a spring, a rubber product, or a hollow plastic product. When the positioning post 201 is placed on the fourth surface a, the contact portion 201a can protrude from the surface of the second surface B. When the contact portion 201a of the positioning post 201 contacts the patch, the positioning post 201 moves upward (i.e., from the second surface B to the first surface A direction) until the contact portion 201a retracts into the positioning hole 101. When the contact portion 201a leaves the patch again, under the action of the reset member 202, the contact portion 201a still protrudes from the surface of the second surface B. Because the weight of the elastic member is not large, one end needs to be fixedly connected to the positioning post 201 so that when the contact portion 201a leaves the patch, the elastic potential energy it has is converted into kinetic potential energy, thereby driving the positioning post 201 to return to its original extended state.

[0046] Referring to Figure 3 and Figure 6 , for the fourth embodiment of the device for thermally sealing and positioning the patch of the present invention, the difference between this embodiment and the third embodiment is that: this embodiment further includes an adsorption component 300. The adsorption component 300 includes a suction cup 301 and a support frame 302. The suction cup 301 is placed in the round hole 102 and fixed to the fixing component 100 through the support frame 302. Among them, the suction cup 301 is placed on the second surface B, and the support frame 302 is placed on the third surface M and connected and fixed through the round hole 102.

[0047] Specifically, the main body of this embodiment includes a fixing component 100, a positioning component 200, and an adsorption component 300. The positioning component 200 positions the patch, and the adsorption component 300 is connected to the fixing component 100.

[0048] The fixing component 100 is divided into a first surface A, a second surface B, and a third surface M. Among them, the third surface M is partially recessed from the first surface A towards the second surface B, making the fixing component 100 in an "E" shape. Here, the so-called "partially" refers to a partial area on the third surface M, and the recessed areas are spaced on the first surface A. Refer to Figures 1 to 3 the fixing component 100 in [reference], where the first surface A is partially and spacedly recessed to form an "E" shape, and the recessed surfaces are all in the same plane, which is the third surface M. The first surface A is provided with a positioning hole 101, and the positioning hole 101 penetrates the fixing component 100. Among them, the positioning hole 101 is a stepped hole, and its interior is provided with a fourth surface a, which is formed by cutting from the first surface A in a circle with a first radius towards the second surface B without cutting through to the second surface B.

[0049] Preferably, the fixing component 100 is provided with a round hole 102, and the round hole 102 is arranged on the third surface M and is a through hole that penetrates the fixing component 100.

[0050] The positioning component 200 is placed in the positioning hole 101 and cooperates with the positioning hole 101. The positioning component 200 includes a positioning post 201. Refer to Figure 5 , the positioning post 201 includes a contact portion 201a and a limiting portion 201b. In the initial state, the positioning post 201 is inserted into the positioning hole 101 and cooperates with the positioning hole 101. At this time, the contact portion 201a protrudes from the surface of the second surface B. When covering the lead-acid battery cover sheet (that is, refer to Figure 1 or Figure 4 ), the contact portion 201a abuts against the cover sheet, and the positioning post 201 vertically expands and contracts, effectively positioning the cover sheet, preventing the cover sheet from being misaligned with the battery cover during heat sealing, and not interfering with the battery cover at the same time. The resetting member 202 is preferably made of brass as a counterweight and is placed from the positioning hole 101 at the first surface A end above the positioning post 201. The counterweight is made of brass with a relatively large density. Its function is to apply a suitable pressure to the positioning post 201 to ensure that the positioning post 201 is in an "extended" state before pressing on the battery cover, effectively positioning the cover sheet. When the positioning post 201 presses on the battery cover during heat sealing, it ensures that the positioning post can "retract" with a small force without pressing the battery cover. The structure of the counterweight has a moderate pressure and a simple structure.

[0051] Preferably, the positioning post 201 and the positioning hole 101 are designed with a relatively long mating distance and adopt an E8 / h7 tolerance fit to ensure a reasonable clearance. The positioning post can slide freely in the installation hole without shaking. When positioning the cover sheet, it can ensure that the position deviation of the cover sheet is less than 0.15 mm.

[0052] In another embodiment, refer to Figures 7 to 16, the fixing component 100 further includes a fixing member 103 and a positioning hole 101. The positioning hole 101 penetrates through the fixing component 100. The fixing member 103 is provided with a circular hole, and a limiting protrusion block 103a is provided on the contour of the circular hole. A limiting groove 103b is respectively provided on each of the two sides of the circular hole, and the connecting line of the two limiting grooves 103b passes through the center of the circular hole. A third elastic member 103c is provided in the groove of the limiting groove 103b. One end of the third elastic member 103c is fixed to the limiting groove 103b, and the other end is connected to the second magnetic block 103d.

[0053] The adsorption component 300 includes a suction cup 301, a support frame 302, and a fourth protrusion 302a. The support frame 302 includes a fourth protrusion 302a, a first magnetic block 302b, a third accommodation space G, a rotation locking member 302c, and a clamping member 302d.

[0054] The rotation locking member 302c is divided into a first layer H and a second layer J. Among them, the first layer H is placed and fixed above the second layer J, and a hole is respectively provided at the center of each of the first layer H and the second layer J, and the two holes are concentric. The radius of the hole in the first layer H is smaller than the radius of the hole in the second layer J.

[0055] The outer contour of the first layer H is recessed from the outer edge towards the central axis of the first layer H to form a fan-shaped groove (the fan-shaped groove does not pass through the center of the circle, that is, only on the semi-circle of the first layer H). A fixing tooth 302c-1 is provided on the inner groove edge h of the fan-shaped groove, and a notch j is provided at the tail end of the fixing tooth 302c-1. It should be noted that the notch j is recessed along the direction towards the central axis of the first layer H on the edge of the fan-shaped groove to form the notch j.

[0056] The second layer J extends from its outer contour in the opposite direction of the central axis of the second layer J to form a third protrusion 302c-2. It should be noted that the number of the third protrusions 302c-2 is not limited to the number shown in the drawings, and the drawings are only for illustration. Preferably, the number of the third protrusions 302c-2 is equal to the number of the grooves between every two adjacent limiting protrusion blocks 103a on the fixing member 103. A locking hole 302c-3 is further provided on the second layer J, and the position of the locking hole 302c-3 is arranged below the notch j of the first layer H.

[0057] The clamping member 302d includes a fixed gear 302d-1, a rotating knob 302d-2, and a rotating connecting rod 302d-3. The rotating knob 302d-2 is connected and fixed to the top end of the rotating connecting rod 302d-3. The fixed gear 302d-1 is fixed on the rotating connecting rod 302d-3, and the rotating connecting rod 302d-3 and the fixed gear 302d-1 are coaxial. When the rotating knob 302d-2 rotates, the connected rotating connecting rod 302d-3 rotates and simultaneously drives the fixed gear 302d-1 to rotate.

[0058] Preferably, the distance from the rotary knob 302d-2 to the fixed gear 302d-1 is not less than the depth of the third accommodation space G, so that after installation, the rotary knob 302d-2 protrudes from the back of the third accommodation space G.

[0059] In this embodiment, the fixing component 100 first engages the third protrusion 302c-2 of the second layer J on the rotary locking member 302c of the support frame 302 with the fixing member 103 through the gap between every two adjacent limiting protrusion blocks 103a on the fixing member 103. By rotating the rotary knob 302d-2, when the rotary knob 302d-2 rotates, the rotary connecting rod 302d-3 connected thereto rotates, and at the same time drives the fixed gear 302d-1 to rotate. The fixed gear 302d-1 drives the rotary locking member 302c to rotate (because the fixed gear 302d-1 is on the first layer H, and the first layer H and the second layer J are fixedly connected to form the rotary locking member 302c), and moves until the third protrusion 302c-2 abuts against the limiting protrusion block 103a, and the support frame 302 is limited by the limiting protrusion block 103a. When the fixed gear 302d-1 rotates to the end of the fixed tooth 302c-1, the rotary knob 302d-2 is stuck at the notch j, because the bottom surface of the buckle 302d is in contact with the surface of the second layer J during the movement process and there is an extrusion force. Below the notch j, a locking hole 302c-3 is provided on the second layer J. When the rotary knob 302d-2 is stuck at the notch j, its bottom surface just disengages from the second layer J. In other words, the rotary connecting rod 302d-3 cooperates with the locking hole 302c-3 to achieve self-locking. Preferably, the fourth protrusion 302a is composed of a cylinder and several convex blocks, and the convex blocks are fixed on the outside of the cylinder. It should be noted that the maximum diameter of the fourth protrusion 302a is smaller than the hole radius of the first layer H, and since the hole radius of the first layer H is smaller than the hole radius of the second layer J, when the rotary locking member 302c is sleeved onto the fourth protrusion 302a through the hole radius of the second layer J, and then the hole radius of the first layer H is sleeved onto the fourth protrusion 302a by extrusion. Due to the mutual extrusion between the fourth protrusion 302a and the hole radius of the first layer H, the rotary locking member 302c is fixed on the support frame 302.

[0060] When the support frame 302 and the fixing component 100 are separated, there will be a groove at the mating part of the fixing component 100 and the support frame 302. If the fixing component 100 and the support frame 302 are not connected for a long time, dust will accumulate in the round hole and it is not very beautiful to have a round hole on the outer surface of the fixing component 100. To solve this problem, in this embodiment, the main body is also provided with a stopper 700.

[0061] The support frame 302 includes a fourth protrusion 302a and a first magnet 302b. Among them, the first magnet 302b is placed in the third accommodation space G. Since the support frame 302 has the first magnet 302b and the fixing member 103 is provided with a second magnet 103d, when the support frame 302 approaches and connects with the fixing assembly 100, a mutual acting force is generated between each first magnet 302b and the corresponding second magnet 103d, and they attract each other. That is to say, when the support frame 302 and the fixing assembly 100 are not close to each other, the third elastic member 103c connected to the second magnet 103d is in a natural state. When the support frame 302 and the fixing assembly 100 are close to each other, because the position of the first magnet 302b is fixed and there is a mutual acting force between the second magnet 103d and the first magnet 302b, the second magnet 103d will move along the direction of the acting force until it receives a resistance to make the force balanced. In this case, the third elastic member 103c connected to the second magnet 103d is in a compressed state under the extrusion of the second magnet 103d.

[0062] In order to connect the support frame 302 and the fixing assembly 100, a round hole is provided on the fixing assembly 100. If the fixing assembly 100 and the support frame 302 are not connected for a long time, dust will accumulate in the round hole and it is not very beautiful to have a round hole on the outer surface of the fixing assembly 100. To solve this problem, in this embodiment, the main body is further provided with a stopper 700.

[0063] The stopper 700 is circular, and at least one first protrusion 701 is provided on the outer contour, and a second protrusion 702 is provided on the outer edge of two opposing first protrusions 701 respectively. Among them, when the first protrusion 701 is matched with the interval between two adjacent limiting protrusion blocks 103a of the fixing assembly 100, the second protrusion 702 is matched with the limiting groove 103b. It should be noted that the stopper 700 is divided into a front side P and a back side Q, and the second protrusion 702 extends from the back side Q to the front side P and does not touch the front side P.

[0064] Preferably, the stopper 700 further includes a second accommodation space N. The second accommodation space N is provided at the center of the stopper 700 and extends from the back side Q to the front side P. The center of the stopper 700 is recessed into the second accommodation space N. A third reset member 703 is provided in the second accommodation space N, and one end of the third reset member 703 is connected to one end of the second accommodation space N.

[0065] The second magnetic block 103d is stepped and in an "L" shape, including a pressing surface r, a sliding surface b, and a connecting surface c. Among them, the second magnetic block 103d is connected to the third elastic member 103c through the connecting surface c, and the sliding surface b moves within the groove of the limiting groove 103b. When the third elastic member 103c is in the initial state, the pressing surface r of the second magnetic block 103d just abuts against the second protrusion 702 and limits the stopper 700. Preferably, the sum of the height of the second protrusion 702 and the height of the pressing surface r of the second magnetic block 103d is equal to the height of the first protrusion 701.

[0066] When in the initial state, at this time the fixing assembly 100 is not close to the support frame 302, and the pressing surface r of the second magnetic block 103d just abuts against the second protrusion 702 to limit the stopper 700. After the fixing assembly 100 approaches the support frame 302, a magnetic force is generated between the second magnetic block 103d and the first magnetic block 302b. Since the position of the first magnetic block 302b is fixed, the second magnetic block 103d moves in the direction of the first magnetic block 302b after being stressed. At this time, the sliding surface b moves in the groove of the limiting groove 103b in the direction of compressing the elastic member 103. At this time, the second magnetic block 103d is separated from the second protrusion 702. Due to the action of the reset member 703, the stopper 700 can reciprocate in the second accommodation space N in the direction between the reverse surface Q and the front surface P.
