Description

Technical Field

[0001] The utility model relates to a detection device for a battery pole position, in particular to an automatic detection device for a battery pole position, and belongs to the technical field of battery manufacturing. Background Art

[0002] Lead-acid batteries are mainly composed of electrolyte, battery slots and pole groups. The pole groups are equipped with busbars and lead bridges to connect all pole groups in series. The pole groups at both ends are connected to the end poles, which pass through the pole holes on the battery slot cover as the positive and negative output and input ends. During the capping operation, the positive pole and the negative pole are respectively inserted into the holes reserved on the middle cover, and the caps on the holes are subsequently removed to expose the positive pole and the negative pole. For the poles formed at one time with the busbar, the material is lead, which can easily cause the pole position to shift during the operation before capping; and for the poles formed by welding, the poles may not stand vertically above the pole group due to operational problems. For the poles with deviations in the lower position, when capping, it may cause the poles to fail to extend into the holes reserved on the middle cover. If the capping operation is completed automatically, it may damage the equipment or even make the battery scrapped. Therefore, before capping, it is necessary to detect whether the pole position of the battery is accurate. For example, the utility model patent application number CN202320941485.9, entitled "A battery pole detection tool", uses a cover plate to simulate the sealing operation between the middle cover and the battery box. If the pole can pass through the detection hole of the cover plate, the pole position is accurate and the battery is qualified; if the pole cannot pass through, it is unqualified. However, this equipment still requires staff to observe, which is not convenient for automatic operation. Utility Model Content

[0003] In view of the above problems, the utility model proposes an automatic detection device for the position of a battery pole, which can fully automatically detect the position of the battery box pole and judge whether the detected battery box is qualified.

[0004] The technical means adopted by the utility model to solve the above-mentioned problems are: an automatic detection device for the position of a battery pole, including a frame and a detection mechanism arranged on the frame, the detection mechanism including an electrically connected detection rod and a detection head, the detection rod is provided with a detection needle for contacting with a bus or a pole so as to make it electrically connected with the pole, and the detection head is provided with a detection hole for sleeved on the outer peripheral side of the pole. During detection, the detection needle of the detection rod directly contacts the bus or the pole, so that the detection rod and the pole are electrically connected, and the detection hole of the detection head is sleeved on the pole. When the pole position is qualified, the detection head will not contact the pole, and no electrical circuit will be formed between the detection rod and the detection head; on the contrary, when the pole position is unqualified, the detection head contacts the pole, and an electrical circuit is formed between the detection rod and the detection head, thereby forming a judgment on the pole position.

[0005] Furthermore, the diameter of the detection hole is equal to or slightly larger than the diameter of the pole hole on the middle cover of the battery box for encapsulating the pole, so as to ensure that the qualified battery box can be capped smoothly.

[0006] Furthermore, the detection hole is an annular through hole, and the height of the through hole is smaller than the height of the pole, so as to facilitate observation during detection.

[0007] Furthermore, the detection mechanism also includes a lifting plate and a lifting power source, the lifting power source is fixed to the frame, the movable end of which is connected to the lifting plate and can drive the lifting plate to move up and down, and the detection rod and the detection head are connected to the lifting plate. The lifting power source drives the detection rod and the detection head to move up and down so as to approach or move away from the pole.

[0008] Furthermore, the detection mechanism also includes a guide post and a guide sleeve, and the lifting plate is connected to the frame through the guide post and the guide sleeve. The guide post and the guide sleeve provide guidance for the up and down movement of the lifting plate.

[0009] Furthermore, the detection mechanism also includes a connecting frame, the detection head is connected to the connecting frame, and the connecting frame and the lifting plate are movably connected, so that the connecting frame can move up and down relative to the lifting plate. The detection head can move up and down driven by the connecting frame.

[0010] Furthermore, the detection mechanism also includes a connecting rod, one end of which is arranged on the lifting plate, and a connecting frame passes through the other end of the connecting rod and can move up and down along the connecting rod. When the connecting frame is subjected to an upward force, it can move upward along the connecting rod.

[0011] Furthermore, a spring is arranged on the outer periphery of the connecting rod, one end of the spring contacts the lower surface of the lifting plate, and the other end contacts the upper surface of the connecting frame. The spring pushes the connecting frame away from the lifting plate.

[0012] Furthermore, the automated detection device further comprises a positioning mechanism, which comprises a clamping plate and a clamping power source, wherein the clamping power source is arranged on the frame and its movable end is connected to the clamping plate. The clamping plate is pushed forward by the clamping power source to clamp the battery box.

[0013] Furthermore, the positioning mechanism also includes a partition, and the partition and the clamping plate are respectively located at two sides of the battery box, and the clamping plate can be driven by the clamping power source to approach or move away from the partition. The battery box is clamped by the partition and the clamping plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model provides an electrically connected detection rod and a detection head, and during the detection process, the detection rod is electrically connected to the pole, and the detection head is sleeved on the outer circumference of the pole. Whether the pole position is qualified is determined based on whether an electrical circuit is formed, thereby fully automatically completing the detection, and the structure is simple and efficient.

[0016] 2. The utility model can complete the detection of battery boxes with different pole sizes by replacing the detection head, and can control the quality of the battery box by changing the size of the detection hole. For example, when the size of the detection hole is only slightly larger than the pole, the position of the pole must be very standard to meet the requirements.

[0017] 3. The utility model movably connects the detection head to the lifting plate. When the pole position deviates and cannot be inserted into the detection hole at all, the pole forms a thrust force on the detection head, pushing the detection head and the connecting frame to move upward, thereby avoiding damage to the equipment.

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary descriptions, and are only schematic diagrams, not actual pictures, and cannot be understood as limiting the present patent; in order to better illustrate the embodiments of the utility model, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Embodiment 1

[0027] The battery box 4 of this embodiment is as follows Figure 5 As shown, the positive plates of the plurality of electrode groups are all connected to the positive electrode column through a bus bar 41 , and the negative plates of the plurality of electrode groups are all connected to the negative electrode column through another bus bar 41 .

[0028] An automatic detection device for battery pole position, such as Figure 1 As shown, it includes a frame 3, a detection mechanism 1 and a positioning mechanism 2. The frame 3 includes a vertically arranged support rod 31 and a horizontally arranged support plate 32. The support rod 31 and the support plate 32 are connected to form a frame structure.

[0029] like Figure 1 and Figure 2 As shown, the detection mechanism 1 includes a lifting plate 102 and a lifting power source 101 (in this embodiment, the lifting power source 101 adopts a cylinder, and can also be an oil cylinder, a motor, etc.), the lifting power source 101 is fixed to the support plate 32, and the movable end is connected to the lifting plate 102, thereby driving the lifting plate 102 to move up and down. The lifting plate 102 is also connected to the support plate 32 at its four corners through four pairs of guide columns 103 and guide sleeves 107 to provide guidance for the up and down movement of the lifting plate 102. In this embodiment, the lower ends of the four guide columns 103 are respectively fixedly connected to the four corners of the lifting plate 102, and the upper ends pass through the support plate 32 and can move up and down relative to the support plate 32. The four guide sleeves 107 are respectively fixed on the lower surface of the support plate 32, and each guide column 103 passes through a guide sleeve 107 respectively, and the guide column 103 moves up and down under the guidance of the guide sleeve 107.

[0030] like Figure 2 and Figure 3As shown, the detection mechanism 1 also includes a connecting frame 105, a detection rod 11 and a detection head 12. In this embodiment, the detection rod 11 and the detection head 12 are both arranged on the connecting frame 105, and the connecting frame 105 is arranged on the lifting plate 102 through the connecting rod 104. The upper end of the connecting rod 104 passes through the lifting plate 102 and can move up and down along the lifting plate 102, and the lower end is connected to the connecting frame 105. The outer end of the connecting rod 104 is also sleeved with a spring 106, one end of the spring 106 contacts the lower surface of the lifting plate 102, and the other end contacts the upper surface of the connecting frame 105. When the connecting frame 105 is subjected to an upward force, it can move upward together with the connecting rod 104, and when the force disappears, the spring 106 pushes the connecting frame 105 to move downward.

[0031] like Figure 6 and Figure 7 As shown, a detection hole 121 is provided at the lower end of the detection head 12. The detection hole 121 in this embodiment is an annular through hole, which is in the shape of a trumpet with a small upper end and a large lower end, and the diameter of the small end of the detection hole 121 can be equal to or slightly larger than the diameter of the position corresponding to the pole hole of the middle cover matching the battery box 4. Figure 3 As shown, a detection needle 111 is provided at the bottom end of the detection rod 11. In this embodiment, the detection needle 111 is used to contact the busbar connected to the pole 42 to be detected, and the detection rod 11 and the detection head 12 are electrically connected. Figure 3 and Figure 4 As shown, during detection, the detection needle 111 sticks to the surface of the bus 41, and the pole 42 passes through the detection hole 121. If the pole 42 is in the correct position, the pole 42 will not contact the detection head 12, so no loop is formed between the detection rod 11 and the detection head 12. On the contrary, if the position of the pole 42 is offset, the pole 42 will contact the detection head 12. When the offset of the pole 42 is not very large, the detection hole 121 is still on the pole 42, and the detection needle 111 is still in contact with the bus 41. At this time, a loop is formed between the detection rod 11 and the detection head 12, and whether the battery box 4 is qualified can be judged by the circuit condition; in addition, if the position offset of the pole 42 is large, the detection hole 121 cannot cover the pole 42, the pole 42 will push the detection head 12 upward, so that the connecting frame 105 cannot be completely lowered, and the detection needle 111 cannot contact with the bus 41. At this time, a loop cannot be formed between the detection rod 11 and the detection head 12. Therefore, a sensor can be set to determine whether the detection needle 111 is in contact with the bus 41 (such as detecting the height of the detection needle 111 by a displacement sensor). If there is no contact, the battery box 4 is unqualified.

[0032] like Figure 4-Figure 6As shown, in this embodiment, the height h of the detection hole 121 is set to be smaller than the height H of the pole 42. When the pole 42 is inserted into the detection hole 121, its top can be exposed from above the detection hole 121, which is convenient for observation. Moreover, for batteries of the same model, the position requirements of the pole 42 can be set by setting the size of the detection hole 121. When the diameter of the detection hole 121 is much larger than the diameter of the pole 42, the requirements for the position of the pole 42 are relatively low; and when the diameter of the detection hole 121 is only slightly larger than the diameter of the pole 42, the position of the pole 42 must be very standard to meet the requirements. In addition, for batteries of different models, it is only necessary to replace the detection head 12 corresponding to different detection holes 121 and adjust the position between the detection rod 11 and the detection head 12 to ensure that the detection rod 11 and the detection head 12 are located at the bus 41 of different polarities, so as to achieve the versatility of the present device.

[0033] like Figure 1-Figure 2 As shown, the positioning mechanism 2 includes a clamping power source 23 (a cylinder in this embodiment, and can also be an oil cylinder, a motor, etc.), a clamping plate 23 and a partition 21. The clamping power source 23 is fixed to the frame 3, and its movable end is connected to the clamping plate 23 and drives the clamping plate 23 to move forward and backward. This embodiment is a structure for simultaneously conveying two rows of battery boxes 4 side by side along the width direction on a conveyor chain. Therefore, a clamping power source 23 and a clamping plate 23 are provided on both sides of the conveyor chain, and a partition 21 is provided in the middle of the conveyor chain along its length direction. When the battery box 4 moves forward on the conveyor chain, the clamping power source 23 pushes the clamping plate 23 to move toward the partition 21 to position the battery box 4 so as to detect the position of the pole 42. After the detection is completed, the clamping power source 23 drives the clamping plate 23 away from the partition 21, releases the battery box 4, and allows the battery box 4 to continue to move forward. There are two pairs of detection rods 11 and detection heads 12 on a battery box 4 to detect the positive pole and the negative pole at the same time.

[0034] In this embodiment, both the detection rod 11 and the detection head 12 are arranged on the connecting frame 105. When the detection head 12 is supported by the pole 42 and the connecting frame 105 cannot be lowered, the detection rod 11 cannot contact the bus 41. Therefore, the detection rod 11 can also be directly arranged on the lifting plate 102 without passing through the connecting frame 105. When the lifting power source 101 drives the lifting plate 102 to move downward, even if the pole 42 supports the detection head 12 so that the connecting frame 105 cannot be lowered, the detection needle 111 can still be lowered to the right position and contact the bus 41, forming an electrical circuit between the detection rod 11 and the detection head 12, and then judging that the battery box 4 is unqualified. Of course, it is best to connect the detection rod 11 to the connecting frame 105 through a spring or the like, so that when the detection rod 11 is lowered to a height slightly greater than the distance between the detection needle 111 and the bus 41, the bus 41 can push the detection needle 111 upward without being damaged.

[0035] In addition, for the structure in the above embodiment, if the distance between the detection rod 11 and the detection head 12 is adjusted so that the detection rod 11 and the detection head 12 respectively contact the bus 41 of different polarities, it is possible to detect whether there is a short circuit inside the pole group, thereby realizing the versatility of the equipment.

[0036] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Technicians in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the protection scope of the present invention, and the protection scope of the present invention should be defined by the claims.
